What's That Bug? does not endorse extermination

About a week ago, I named the prettiest Gold Fledgling Angelfish Paris, and this evening I moved Paris and two other gold fledglings born last summer into the aquarium with Boris and Medea Luna.

I was nervous about introducing the youngsters into the aquarium with the older pair.  The older pair acted aggressively at first, but they seem to be tolerating the gold relatives, but Boris and Medea Luna are showing signs of getting ready to spawn.

I want to raise a school of golden angelfish with internet profiles and try to get more store credit for them from Tropical Imports.

I traded 13 young Angelfish and the runt from last year for a $2o size of flake food, and I learned that the color of Angelfish has no bearing on their value.  With Angelfish, it is all about size.

It has been a rocky beginning for the most recently laid batch of eggs produced by Lefty and Digitalis on May 24.

Shortly after the eggs were laid, the two month old fry that were still with the parents began devouring the eggs.  All 39 fry that were removed that day had fat little bellies full of eggs.  The number of eggs that were devoured must have been over 100.  Yesterday, the remaining hatchlings began to swim freely and eat newly hatched baby brine shrimp.  There appear to be about 50 that escaped being eaten as caviar.

The light was bad yesterday when I tried to take some photos, and today, I captured the late afternoon sun shining into the tank, but the reflection coming from the south window is a bit distracting.  The parents are quite protective of the fry and they attempt to keep them in a tight school, with stragglers captured in the mouth and promptly spat back into the crowd.

Update:  June 7, 2010
Yesterday, when a fly was buzzing at the window and casting a shadow onto the aquarium in the late afternoon light, Digitalis charged at the shadow.  The fry were on the other side of the aquarium, so I looked a bit more closely.  The previous day, I noticed both Lefty and Digitalis picking at the algae covered driftwood in the aquarium.  There was a huge clutch of eggs on the branch.  The free swimming fry are about two weeks old now, so they are too young to eat eggs or younger siblings, but it is odd to have a second spawning follow the previous spawning so closely when there are surviving fry.  It will be interesting to see what happens as the new batch of fry will become free swimming just as I have to leave town for a week.  I hope the neighbors are game for the challenge of feeding hatchlings.

I just noticed that Lefty and Digitalis have laid eggs on the leaf of the speckled sword plant, and there are still at least 30 fry in the aquarium with them.  I just captured 10 fry in an attempt to remove all remaining fry to the grow out aquarium.
In my second attempt, I caught 29 more small fry, and that appears like it may be all of them, though they are hiding quite well.  All the 39 fry that were captured had fat round bellies, and I watched them eating the spawn.  It must have been an enormous spawning since there are still quite a few eggs remaining.  When I looked at the aquarium this afternoon, things just seemed different.  The fry were not clamoring around the glass with the parents.  They were hanging out in the rear of the aquarium, near where the spawning had occurred.

Lefty and Digitalis’ eggs hatched sometime yesterday because they were gone from the leaf when I returned home at about 8:30 PM.  I noticed a small cluster of hatched fry wriggling on another leaf.  This is not a large hatching.  It will be interesting to see if they are raised by the parents, or abandoned for a larger brood.

There are about 30 fry wriggling on the leaf of the sword plant where they were moved shortly after hatching.  The parents do not seem interested in moving the fry again.  The photo taken today is hopelessly blurry.

Lefty and Digitalis' Fry: three days after hatching

May 31, 2010
About 50 fry became free swimming today, and they had their first meal of newly hatched brine shrimp.  The parents are protective, and the fry are quickly herded back together if any individuals stray from the school.

By the time I decided to take some photos, the light in the aquarium was very low since this birthing aquarium does not have a light fixture.  The only light is daylight coming from windows on the west side and from the north porch with the awning.  The back of the aquarium has much algae.

Aquarium Comments – Cycling
May 24, 2010
Yes, I know, MTS (Multiple Tank Syndrome) has an incredible effect. Anyways, I greatly appreciate you putting information on cycling in your site, most people overlook this essential process.
However, I would like to politely point out that there are many ways to successfully cycle an aquarium without the use of live fish. Here on Fishlore ( we find this rather ineffective, as well as stressful to the fish.
I’m not saying that you didn’t do the right thing. I have to, again, express my gratitude of you placing this entire process on your site, so all other new fishkeepers can read and understand.
For more information on the Nitrogen Cycle and how to cycle an aquarium without using fish, I would recommend this excellent page:
In addition, any questions you may have can be answered if you join the forum.
Thank you for hosting this great website, again, and showing off your gorgeous aquarium and fish. Its not every day you see angelfish breeding as much as yours, so I can be sure that you are taking good care of them!
Brian (Elodea on FL)

Thanks for the links Brian.  Cycling our aquaria was quite an ordeal.  Though, in general, we think our skill as a freshwater aquarist is above average, we still have two factors to try to correct.  Algae (hair algae in one aquarium and blue-green and brown algae in the other two) proliferates and the plants are not thriving.  Perhaps will provide us with some assistance.

Update:  July 14, 2017
Though the time for cycling our aquarium has long passed, we received the following request from Emma, and upon reading it, we decided it would be appropriate to share the information she provided.

Heyyy Daniel
Just wanted to reach out after coming across your page …
Here’s the thing, we recently published a much better guide on the Nitrogen Cycle with brand new custom graphics, which you can see here:
Thought it might make a nice addition (or replacement) link on your page.
It would awesome if you did. And of course, we’d be happy to share your article on our social media channels as a way of saying thanks!
Either way, keep up all the good work.

When I took the last of the fledgling Angelfish to Tropical Imports last week, all I had left were three gold Angelfish and the runt of the year.  Now they are living happily with their younger relatives.  I want to save all the gold Angelfish until I have a nice school of Goldies to sell for a higher price toward credit for food.

I don’t like naming the Fledglings since I am just getting rid of them, but I am thinking of naming one of these beauties Paris.

15 + 45 = 60 Small Fry in the Grow Out Aquarium
May 21, 2010
I just moved 15 more fry from the birthsite aquarium to the grow-out aquarium.

15 + 60 = 75
May 22, 2010
I moved 15 additional small fry today to make a total of 75 small fry and 4 older relatives in the grow out aquarium.  The largest of the small fry are just about ready to be taken to Tropical Imports at $1 credit each.

Yesterday, just as I were preparing to leave the house for an important Land Use meeting, I witnessed an horrific scene in the community aquarium.  I had wondered why Boris and Media Luna had not laid any eggs since the introduction of the 8 fledgling adolescent Angelfish into their tank about a month ago.  I thought that perhaps the increase in the species population had upset their reproductive clocks, but I was wrong.  The reason was quickly revealed.
After a partial water change, Media Luna began to lay eggs on the filter intake while Boris chased away the other fish.  Young Angelfish have ravenous appetites, and they will eat twenty times a day if fed that many times.  The fledglings were not being intimidated by the larger mated pair, and with each row of eggs, several youngsters would sneak in and eat the eggs.  The pair had no problems chasing away tetras and rams, but their younger relatives were like a pack of wolves, patiently waiting for a hole in the defense line to swim through before devouring the fresh caviar.  If I want to raise more youngsters, I need to take these 8 beautiful fledglings to Tropical Imports.  At this point, I hope to get a better price (credit toward food) as they are nearing sexual maturity.  Alas, there are no photos to accompany the carnage.

I moved 10 additional small fry out of the aquarium with Lefty and Digitalis and placed them in the grow out aquarium.  I have now moved 45 small fry and it seems that close to 45 still remain with the parents.  I want to take the 8 adolescents to Tropical Imports today, and I hope to get an exchange rate of $4.00 per fish to apply towards all the food I need.

Since I took photos to show how large the fry born last August have grown, I can try to catch them and transport them today.
