Angelfish and Corydoras fry

26 Aug

These baby fish are at a friend’s house. He’s an expert Angelfish breeder who also bought some Peppered Corydoras in the hopes of spawning them in the future.
The future came fast. His Cories grew like mad, the females are the biggest fattest things you can imagine, and they are spawning all of the time. He has hundreds of babies and more to come.
Notice this neat little system he uses to get the babies started in life. He has them in glass mason jars that are floating in a 5-gallon fish tank. This way, he only needs the single heater in the aquarium. He drops an airline into each jar, makes frequent water changes, and feeds them live baby Brine Shrimp.

In this next picture you can see some baby Angelfish, too.

I should have photographed his homemade Brine Shrimp hatchery. He decapsulates the shrimp eggs and staggers their hatching to ensure a constant supply for all of the babies. Sounds like a future blog post if he doesn’t mind!

More Angelfish eggs

29 Jun

This time I was ready. When the Silver Angels spawned I had a little tank prepared with clean water, an air pump, the right temperature, and some Methylene Blue as a fungus inhibitor.

Here it is:

The eggs are on the plastic filter tube that was in the 55 gallon aquarium. I don’t need a heater in this tank, I am keeping the room about 80F degrees. (which is not too hard since it is 97F outside)

Zebra Danio babies go into 30-gallon pond

9 Jun

I have some Zebra Danio fry that became free-swimming yesterday so I netted up a bunch and put them into the 30-gallon pond. Before I did that, I swapped out the plastic box filter for a sponge filter. The babies can’t get sucked into a sponge filter.

It looks like I netted about 50 babies but there are 30 more in the 10 gallon tank. I’ll do this again tomorrow, and the next day, until I get them all. If I was smart I would take the 10 gallon tank outside and dump the whole thing in.

It was hot day, in the high 80’s F, and the pond is right at 80F, perfect for the little Zebras.

The plastic container with the Zebra babies is floating in the pond, allowing the temperature to get to 80F. Then I dipped some water from the pond into the container so they get used to the different water quality.

Quickly now, I plan to spawn some Black-Skirt Tetras and add the fry to the little pond also. As soon as I get all of the baby Zebra’s outside I’ll set up the 10 gallon tank for the Tetras.

Spawning the Zebra Danio, post #4

27 Apr

The Zebra Danios were hatching yesterday.
The best way I can describe them is to say this:
Picture the smallest glass sliver you can imagine. No, smaller than that. Keep trying…YES , you got it. Tiny, huh??? That’s a baby Zebra Danio.
Now, a day later, they are still tiny but have a darker coloration. They are not “free-swimming” yet, they lay on the bottom absorbing the remaining nutrition from the egg sac.
I grabbed a bucket of “green water” from my turtle pond. That is algae-rich water, which will also contain many “animacules”, small plankton-like creatures that the baby fish can feed on. I let the green water warm up and I have been adding a few cupfuls during the evening while I am home. After a few days of this I will get a brine-shrimp culture going.
You may not have turtle pond to gather green water (why not?) so I will post information about the feeding of very small egg-laying fish. I am referring to “infusoria”, again, VERY small animal life that very small fishes can feed on.
Here’s a pic of a few baby Zebra Danios. I have NO IDEA how many hatched. I saw the parents munching away at their own eggs so there may not be very many, but that’s OK. I am not trying to get rich by raising Zebra Danios.

Look along the silicone sealer to see three baby Zebras.

Spawning the Zebra Danio, post #2

22 Apr

A friend (Mrs. D) has a 29 gallon tank with about 10 Zebras Danios. I asked her if I could borrow a few of her fish for a week or so.

Catching these fish was comical. It was also pathetic. Mr. D and I tried to catch the fish using fairly small nets, plus Mr. D’s net had a big hole in it.  Amazingly, he was able to catch the two males I wanted, whereas I caught the fat egg-laden female. This 5 minute task only took an hour or so.

I felt bad that the tank was tore up so badly. We had to remove rocks and plants, and generally made a mess of it. I mumbled something brilliant like “It’s good for a tank to get stirred up a bit now and then.”

Mr. and Mrs. D's nice-looking 29 gallon tank, before I arrived. Near the surface you can see the Zebra female carrying eggs.

The female is by herself, for now,  in a 10 gallon tank with only a heater and an airline. If we get any babies I’ll get a sponge filter going in there right away.

On the bottom of the tank I put a piece of plastic “light diffuser”, something that can purchased at a hardware store or place like Home Depot. I have the diffuser raised off of the bottom of the tank about half an inch.  Zebra Danios are egg scatterers so we expect that many eggs will fall through the plastic onto the bottom of the tank.

That’s also why I have the water level at about 4 or 5 inches. If the tank was full and they started scattering eggs, the parents would eat many eggs as they sank. Even with this setup lots of eggs will get eaten.  I added  some plants to encourage the Zebras to feel that this is a good place to spawn.

This momma Zebra has been through a lot this past day. She looks almost miserable to me, she is so full of eggs. I would normally wait a few days and let her get comfortable in the breeding tank but I just have a feeling that she needs to pop, so I may put in a male tomorrow morning.

The Firemouth Cichlid eggs-periment

22 Apr

I had always perceived Firemouth Cichlids as being quite aggressive fish, only suitable for a tank containing other aggressive fish like Convict Cichlids and Jack Dempseys.

Various internet sites suggest that they can be in a community tank of peaceful fish like Swordtails and the larger Tetras.

Every time I passed a tankful of Firemouths I would look at them  longingly. I like them. I like their colors, I like their shape. At our local fishshop I asked one of the owners, “Are the Firemouths very aggressive? I have been reading that they are not too bad.”  She literally snapped at me, “See their name..CICHLIDS…aggressive!” Or something like that. Of course, she would sell me all the Angelfish (a Cichlid) I would want.

So I bought my Firemouths somewhere else, four of them. Only an inch long, I put them in a 29 gallon tank with a bunch of Green Swordtails that I raised. They get along great with the Swordtails but they beat the heck out of each other, and I have had to move the losers around a bit to let them recover.

I haven’t written a post about them before mainly because I never got a satisfactory photo of one of mine. But now, I have to post this. The largest and strongest two Firemouths have grown to over 3 inches long, and they have been just terrible to the other two Firemouths. They are still good tankmates to the Platies and Swordtails.

Here is why they are so territorial right now. EGGS! Laid on a piece of wood right in the middle of the tank. What am I going to do with these? Honestly, I don’t have a clue right now. I’ll leave a dim light on in the fish room so they can guard the eggs at night.

Lionfish in trouble

9 Apr

Oh my goodness, my Dwarf Lion acts so healthy but I think he/she is in trouble. I just saw this bulge in the anal area, a prolapsed intestine I believe. What can I do? Nothing much I’m afraid. I’ll stop feeding the Lion for awhile, and make a water change soon.

I fear the worst. How can this just pop back inside? Not likely. And is it my fault? Did I overfeed the Lion and cause this?

This is my favorite fish. The prettiest,  most amazing fish.
