What's That Bug? does not endorse extermination

This morning I noticed that Angelfish Boris and Media Luna laid eggs again.  Their last two spawnings had a very high mortality rate.  The spawning from approximately two weeks ago only has two fry.  The spawning from about four weeks ago has about 13.  Once the fry become free swimming, they start to die.  The most recent hatching was one of the largest hatchings, but within a week, there was a great die-off.  It is possible that the time I introduced two generations to the nursery tank together, there was a similar die-off, and I accused the elder siblings of killing their younger brethren.  I currently have 13 fry in the nursery aquarium and two in a bowl inside the nursery aquarium.  I will transfer the 13 to the grow out aquarium after taking the largest fry in there to Tropical Imports to trade for frozen brine shrimp.

Update
September 19, 2009
Much has happened since the August posting.  I never removed the fry from the community aquarium and all were eaten.  The two fry in the bowl were raised in the nursery aquarium alone after their 13 older siblings were moved to the larger aquarium.  The two fry that were alone grew quickly.  Last week they too were moved to the community aquarium after I took the the 10 largest youngsters to Tropical Imports to exchange for food about two weeks ago.  Lefty and Digitalis are still with their most recent spawning, but I think Digitalis is filling with eggs, so I should catch the fry and remove them to the grow out aquarium.  First, I have to catch the largest fry and take them to Tropical Imports.  The largest individual I had, I gave to Daryl next door to add to his aquarium.  Yesterday, Boris and Media Luna laid eggs on a leaf of a new plant I bought two weeks ago.  I have also begun to use a product to remove algae, and it is working.  The product is called Algaefix.

Today I gave the largest fledgling Angelfish that was laid on March 31 to Daryl next door.  This Angelfish is now four months old and looking quite graceful.  I also caught 12 Angelfish from the grow out aquarium and traded them for two packs of frozen baby brine shrimps at Tropical Imports.

The latest spawning from Boris and Media Luna has had a high mortality rate.  Many of the fry are dying in the small plastic container floating in the 10 gallon nursery tank.  I am currently moving all the fry from the nursery aquarium to the grow out tank so I can try to save the couple of remaining youngest fry.  I have moved 25 and then 13 and then 12 and then 5 for a total of 55.  I was not trying to catch the largest fry, but moving all I caught.  It seems the smallest fry that were just moved are being picked on by the larger fledgling fry.  I may try to take 10 more of the largest to Tropical Imports tomorrow.

240-13+55= 282.  There should be 282 fry in the grow out tank, but I really think it is more likely there are half that number.

Meanwhile, Lefty and Digitalis spawned several days ago and the fry became free swimming two days ago.  There are about 60 or more young fry currently swimming with the parents.  The fry raised with the parents seem to grow so much faster.

Update:  August 10, 2009
Boris and Media Luna spawned yesterday.  I need to get all the fry out of the nursery aquarium and clean it.  Then I can move the fry in the floating box, less than 20, to the nursery aquarium and prepare for the newest fry.

I caught 15 of the largest fledgelings from the grow out aquarium and am taking them to Tropical Imports today.  that will leave 267 (considerably less) remaining in the grow out aquarium.

I then moved the final 25 fry from the nursery aquarium into the grow out tank.

FInally, I cleaned out the nursery aquarium and moved 18 fry from Boris and Media Luna’s spawning of two weeks ago.  They are about the same size as Lefty and Digitalis’ week younger fry.

Where we left off …

There should be 201 fry from various generations and parents in the grow out tank now.

Saturday August 1, 2009
I have currently captured 25 fry from the nursery aquarium to move to the grow out tank.  This is necessary since two days ago, I siphoned out a small quantity of fry from the community aquarium after allowing Boris and Media Luna to care for their hatchlings.  This would bring the total in the grow out tank to 226, given that there may have been some losses.

Also, yesterday, I noticed that Lefty and Digitalis had spawned again, and it was a large number of eggs.  Sadly, today all of the eggs look white.

I caught 14 more fry to move (total 240).

We took some photos of Lefty and Digitalis and the Fry this afternoon.  We planned to start moving the fry because the fry are beginning to pick at their parents.  The fins are getting ragged.  We also caught 11 of the largest Anglefish from the 50 gallon aquarium (which we now believe is a 40 gallon aquarium) and sold them to Tropical Imports.  We got credit towards some food.

After catching the 11 fish, there should have been 132 remaining if none died and vanished.  I then added 36 fry from Lefty’s latest brood, bringing the total in the 50 gallon aquarium to 168.  One of the new transfers did not look well and may have been injured in the netting process.

Tomorrow I may try to transfer the remaining fry from Lefty’s tank and the largest fry from the nursery aquarium.

Yesterday, Boris and Media Luna spawned again on the heater.  I knew this was coming as they got territorial the night before and chased everyone away.  They also were cleaning the heater and the filter intake pipe.  I shot some photos today.  Boris is in the shot with the eggs.  I expect them to hatch tonight or tomorrow morning.  It is very warm in LA right now.

I also captured 16 more fry that were in Lefty and Digitalis’ tank.  The young fry are picking at the parents and the fins are beginning to look ragged.  The fry are definitely large enough to move to the grow out aquarium.  Total should be 184 if there have been no casualties.  I caught the final (I think) 9 fry and moved them as well, bringing the total to 193-1.  The 1 was a casualty.  One fish in the aquarium got squashed between the glass wall and the plastic tank.

Update:  More fry moved and Boris and Media Luna spawn again.
July 26, 2009
Today I moved 8 fry from the nursery aquarium to the grow out aquarium.  These were the biggest fry I could catch.  I need to make room in the nursery aquarium because Boris and Media Luna spawned again a few days ago.  The fry hatched yesterday.  I also noticed that there is at least one fry remaining in the tank with Lefty and Digitalis, but I was unable to catch it and haven’t even seen it again since noticing it this morning.

Later in the day I caught the remaining young fry in Lefty’s aquarium.  There should be 201 fry from various generations and parents in the grow out tank now.

The Carnage
Last night, before going to bed, we released the week old hatchlings into the nursery aquarium with the two week older siblings.  Though there was a difference in size, we thought all would be fine.  About an hour after turning on the light this morning, we realized we had made an horrific judgment error.  One of the larger fish in the tank had a younger sibling in its mouth.  Most of the younger fish were floating dead or dying.  We don’t know if they were picked to death, or if they were partially chewed and disgorged, but we suspect since a fish will attempt to eat most anything that will not eat it, there was just too much of a size discrepancy for the two generations to coexist, at least until the youngest had gotten more experienced.  Sadly, we have lost nearly the entire generation.  We managed to rescue two little guys and they are once more quarantined.  The largest of the second generation seems to be coexisting right now with the larger siblings

We got home from shopping today and noticed that Boris and Media Luna were in the process of laying eggs on the uppermost Amazon Swordling. There was evidence last night that this might happen. All fish were being chased from the right side of the aquarium, and Boris was moving sideways through the water. Breeding tubes were showing. Just one week ago the wrigglers were removed with a turkey baster.

I am not sure if I have the room to try to raise this batch of fry. Time will tell. Media Luna is reflected in the glass in some of the photos.

Update on three recent spawning
6 July 2009, 10:20 AM
Yesterday, Boris and Media Luna moved their freshly hatched wrigglers to a lower leaf.  This coincided with the addition of 7 Algae eaters, Otocinclus species, that I added to the community aquarium.  I still haven’t decided what to do about this spawning.

Lefty and Digitalis have swimming fry in the aquarium.  They are growing, but the numbers may be declining.  Signs of a predator lurking in the aquarium, perhaps?

Boris and Media Luna’s previous spawn are doing well in the nursery aquarium.  They are growing.  They are about three weeks old now.

Update on three recent spawnings
12 July 2009, 2:08 PM
First off, this is the first addition to the website from the brand new fast computer.  We expect to be able to make many more postings each day now.  Several days ago, possibly Thursday, I moved many of Boris and Media Luna’s latest fry with a turkey baster.  I left about 30 fry in the tank with them.  They had been moving the fry at least twice a day.  From the leaf, to the glass, back to the leaf and back to the glass.  I placed the wrigglers in a plastic box that attaches to the side of the nursery aquarium.  The fry have been swimming for two days now and they are eating well.  They are significantly smaller than the previous batch of fry from the same parents, and I am a bit nervous to release the younger siblings into the same 10 gallon aquarium.  I think I will do it tonight as I fear the small box, that can’t hold more than 2 cups of water, is far too small for the growing fry.  The parents tried protecting the swimming fry for about a day.  I watched the last 6 fry get eaten by the Cardinal Tetras when the parents were distracted.

Boris and Media Luna’s older fry are starting to look like cichlids, but not like angelfish yet.  They are about a month old.

Lefty and Digitalis are surrounded by their fry in their own aquarium.
