Silver Angelfish fry

6 Jul

The latest batch of Silver Angels became free-swimming today, so I cleaned out the 30 gallon pond a little bit. I want to leave it natural, with all the little micro-organisms for the baby fish to eat. Tomorrow morning, while it is a decent temperature, I will put the baby Angels outdoors.
I had baby Zebra Danios in the pond, and I took them out today. My next post will show them.

A lot of eggs did become white with fungus,but about 50 babies hatched.

The plants in the little pond are doing great. I took out the Zebra Danios, changed about half of the water, put the plants back in, and will add the Angels tomorrow.

It’s the lazy man’s way of raising fish fry. Let Mother Nature do it.

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.

Caviar, anyone? (Danios, Angels, Turtles)

I’ve got some Zebra Danio eggs that are hatching. My plan is to wait a few days, until they are free swimming , then transfer them slowly into my 30 gallon pond and forget about them for a month.
Look closely at this photo to see a Zebra Danio still in the egg but curved into a little “C” shape.

Last week I put some Silver Mollies and Endler’s Livebearers into the turtle pond. Not for food, the turtles are too lazy to chase them.
We had a little cold snap, nights in the upper 40’s F, but I can see a number of baby fish in the pond now. Not sure if they are Endler’s or Mollies. Well, duh, must be both.

Also, right now, my Silver Angelfish have spawned, again, on the filter intake in the 55 gallon aquarium. So I am puzzling over this. Should I try to save this batch? I LOVE Silver Angelfish.

And in a 10 gallon tank my female Red Swordtail is filling up with babies. I think I missed her last birthing.

I need to toss in a handful of hornwort (floating plant) for the babies to hide in.

The five babies from her first pregnancy are doing great, getting fat and turning nicely red, although they look orange in my photos.

Note how perfectly I focused on the rock.


Note how perfectly I focused on the wood.

And what have we all been waiting for? Yes, it’s turtle time again. Turtle baby Number Two has hatched. He is still sitting in the eggshell.

The first baby still has the yolk sac attached to his belly, but he is crawling around a bit.

Quilt Batting as filter material

7 May

If you use LOT of filter wool, either in indoor tanks or a pond, consider buying Quilt Batting. The regular batting is denser than Aquarium filter wool. The batting does not remove the finest algae particles but it collects more than the Aquarium wool.

I cleaned the pond filter a few days ago. Here is that process. It’s a cheap filter, supposed to work mechanically¬† (with filter wool ) but also biologically, with plants growing in the filter itself. Unfortunately, it is so brutally hot on the South side of my house that no plants have survived in to the Summer months. Plus, the turtles eat any aquatic vegetation in the pond, so this filter cannot keep up. Still, I would recommend something similar for a goldfish pond. (NOT a Koi pond, same problems as the turtles)

The empty filter. By the way, this is just the “filter box”. The pump is underwater in the pond and tubing runs into this box then overflows into a small stream.

2 bricks on the bottom. The water comes in through the white PVC tube at the back left. The bricks will support the rest of the filter material so the water can flow around underneath and percolate upwards.

The white grid is some of that “light diffuser”, plastic stuff that I use to breed egg-scattering fish.

Plus some Lava Rock.

Quilt Batting.

Another grid on top.

A strainer around the outflow.

Rocks to hold down the grid and the strainer.

And I still have green water.

It’s green, it’s clean, but the fish cannot be seen.

I realize that I failed to show you the real fun part, which is crawling and crouching while removing heavy, nasty, disgusting old filter material. Since I forgot to take photos of that please use your imagination.

Updates on Zebra Danios, Firemouth Cichlids and Turtle eggs.

30 Apr

It’s been chilly around here but it finally warmed up late this afternoon.

The turtles are out basking:

See how green the water is? I can’t see the goldfish or Rosy Red Minnows. I know one reason why the pond is so green:

Those white globs near the water aren’t turtle eggs. They are globs of poo from a bird known as a Grackle. The Grackles are big , black, glossy beautiful birds but when they breed they keep their nest clean by picking up poo and carrying it to a body of water and dropping it in. The pond is getting over-fertilized. Our birdbath also gets very messy with Grackle poo.

But let me tell you about the 5 turtle eggs! I uncovered them for the first time since I put them in my little almost-homemade incubator. The first egg I uncovered was shriveled, and nearly bent in half. I thought , Oh No what have I done! Too dry? But no, it’s mildly damp and warm in there. The other four eggs are looking full and healthy. It’s possible we will have baby turtles within a month!

This is the egg that is not developing.

I think there's a baby turtle in this one.

I finally saw the baby Firemouth Cichlids tonight but could not get a photo. The babies are being herded on the bottom of the tank behind the rock in this picture. I wonder how many there are. It looks like 30 or 40 , maybe 50. I suppose I need to remove them as soon as they become unmanageable to the parents.

The baby Zebra Danios became “free-swimming” today. That means instead of being little tiny slivers that hug the glass, they are actually out swimming around looking for food. It’s impossible to see much in this video but I think there are approximately 50 babies.

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.
