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.

I just caught and moved 5 more of Lefty’s and Digitalis’ fry that hatched exactly 2 months ago.  There are now 25 younger siblings and 4 older siblings, three of them gold.  There are a few fish in this new generation that have only 1 pectoral fin.  By my count, 2/25 of the moved fry have 1 pectoral fin, but these handicapped fry do not seem in any way less hardy than their siblings.  It is quite odd though that there are fast growers and slow growers in each batch, and with each passing week, the size differential seems greater.

After moving 5 fry, I caught some Mosquito Larvae to feed the fish, and I decided to set up a “studio” in the back yard with white paper so I could photograph the Mosquito Larvae, making them the Bug of the Month for May 2010.  I have been feeding the Angelfish Mosquito Larvae since last year, and the fish really love them.

Update:  May 5, 2010
I caught and moved 10 additional fry to the growout aquarium today.  I have moved 35 from the newest spawning to date.

Last weekend I took the last ten fledgling angelfish to Tropical Imports and traded them for a new timer.  The growout aquarium still has three gold angelfish as well as the striped runt from last summer’s spawnings.  Then I captured 5 of the largest fry that are being raised by Lefty and Digitalis and I moved them into the growout aquarium.  They are doing well with their older siblings, though they may be older cousins.  I do not keep track of the parentage once the fry are moved to the growout aquarium.  I just caught 6 more fry and they are acclimating to the water change before I release them into the growout aquarium.  I hope to move several additional batches of the larger fry to thin out the ranks in the parent’s tank.  Lefty and Digitalis are feisty and protective parents.  They splash water out of the aquarium when I feed the fry, probably because they remember loosing their previous generations of fry to the net.  These fry were spawned on February 24 and became free swimming on March 2, so they are nearly two months old.  I will try to take some photos to add to this posting.
