Two weeks ago, as Lefty and Digitalis were preparing to lay more eggs, I decided to get a new 10 gallon nursery aquarium since Daryl asked for the borrowed aquarium back.  On July 9, I wrote:  “
I caught 17 more fry for relocation.  Total 63.  There are at least 21 remaining.“All of the fry left with the parents and they eventually vanished as did the new batch of eggs.  It’s a mystery.  Meanwhile, there was some mortality among the 63 fry that were put in the nursery aquarium in the bathroom.  There are probably at least 30 fry still alive, though it is difficult to count them.  I took some photos a few days ago.

The fry are eating well and growing and the largest are beginning to look more like Angelfish.  I would like to move them into the grow out aquarium within two weeks, but first I will need to take the largest youngsters to Tropical Imports to trade them for store merchandise, perhaps a Clown Loach to eat snails even though the Clown Loach is not an Amazon species.

The spawning that prompted moving the fry a few weeks ago vanished, but about a week and a half ago, I placed a piece of slate in the aquarium with Lefty and Digitalis.  Within days, they spawned.  This was last weekend.  Many eggs were not fertile, but they did hatch and the wrigglers were moved around for a few days.  Monday, August 2, they began to swim and for the past two days, they have been eating newly hatched baby brine shrimp.  There are about fifty fry.  The fry that were moved to the 10 gallon aquarium should probably be moved to the grow out aquarium, but not until I take the largest inhabitants to Tropical Imports.

Yesterday I noticed a huge clutch of new eggs that Lefty and Digitalis laid on the filter intake tube.  The filter is not on.  The last eggs were laid 16 days earlier on June 22.  Yesterday I bought a cheap 10 gallon aquarium and a new heater.  I set it up last night and caught 4 fry and moved them into the new tank to make sure they would live.  I then caught 15 more and added them this morning.  I just caught 21 additional fry and they are acclimating to the temperature change.  40 fry have been removed from the aquarium with the parents and new eggs, and there are still some fry remaining and needing to be relocated.  Though the parents did not show any signs of wanting to eat their older fry to defend the new eggs, I do not want to take the chance.  The fry that disappeared when I was away, and the speculation is that the parents ate them to prevent them from eating the new eggs, were older and larger.  Perhaps these current fry are not a threat to the new eggs.

Lefty and Digitalis have always been very aggressive when it comes to defending their brood.  They have consistently splashed water at me while I am feeding the youngsters eyedroppers full of newly hatched baby brine shrimp.  Yesterday, while feeding the hatchlings that have only been free swimming for a few days, I was surprised by a large splash and an adult angelfish atop the aquarium glass.  It had escaped the aquarium through an inch and a half gap between the glass and the rear edge of the aquarium where the filter pipes enter and leave the aquarium.  I have never thought I needed to block the gap as I did not think an angelfish would jump.  Apparently parental protection instincts allow they not terribly aerodynamic looking angelfish to go airborne.  It all happened so quickly, but I scooped up the fish and tossed it back into the aquarium.  It was Digitalis’s behavior that seemed noticeably changed after the incident, so I suspected she had leapt out.  About an hour later, I noticed a small wound on Lefty that looks like a scrape.  Perhaps it was caused by the glass, or perhaps my hasty handling of the leaper with dry hands.  I added 10 milliliters of Stress Coat to the water to help Lefty generate a protective slime coating on the wound.  Despite the leap, Lefty’s behavior continued to be very aggressive in defending the youngsters when I approached the aquarium.

The other pair of Angelfish, Boris and Medea Luna, who have not had a viable spawning since late last summer, have always defended the eggs against the tank mates by propelling themselves sideways through the water so that they look like manta rays.  I can’t help but wonder if there are other reports of Angelfish leaping out of aquaria.  I have a photo taken of the family the day before the jump.  Lefty appears to be recovering nicely, and both parents eagerly eat mosquito larvae I catch in the yard, but Digitalis stays close to the small fry.

Lefty has recovered and is doing nicely.  The young fry are growing, but I am concerned what will happen if the adults spawn again.  In preparation, I took the twenty largest youngsters from the grow out aquarium and traded them for frozen and live food today.  I contemplated getting a Plecostomus to put in the community aquarium, but I don’t want it to eat the eggs that are laid there.

Upon my return from visiting mom in Ohio, I learned that neighbor Sandy who fed the fish noticed that all the 3 week old fry being raised by Lefty and Digitalis had vanished.  Though I don’t know for certain, I saw that there were new eggs.  Perhaps the three week old fry went from being children that needed to be defended to a cannibalistic hoard trying to eat the new eggs.  I suspect the fry became a meal for the parents in the interest of defending their new brood.  The eggs hatched about Thursday, June 24, and the parents have moved them several times.  I ran the filter for a few days and changed some water, but I shut the filter off again since a favorite place to place the brood is on the filter intake tube.

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.

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.
