Long story short I have maybe 8 albino cory fry, maybe 2-3 days old. I gave the story about what happened with the eggs at the end of the post.
They are in a 10 gal with heat, black sand and a little brown gravel. It has an air powered sponge filter. It has an emperor 280 (280 gph ) biowheel filter that I ran for the eggs but do not leave on now.
The biggest problems are tons of fungus in the tank and what to feed. Some of the fry are still extremely tiny (the fungus blooms are much larger than the fry so any kind of power filter that will suck them up will suck up the fry. The fungus keeps attaching to the sand, weighing it down which is also a problem. I have basically been spending a couple of hours a day manually cleaning the tank. I use a syringe to suck up bigger stuff, a power siphon to suck up some (water change), and then I run the hose on the power siphon into the back of the emperor 280 filter so it gets filtered and spills back into the tank. It would be great to run the emperor filter to stir things up for the siphon but it creates a lot of water flow (the intake is covered with fine fabric so it can not suck up fry but they could get sucked to it). I do turn it on for 10-20 seconds occasionally to stir things up but the fry do not like the heavy current (that I can tell). It seems clean but any time I turn on the emperor filter, its stirs up a bunch of stuff I didn't seem before. How much water current can they take for short or long periods of time?
Is there a better way? I could manage a smaller filter but there is still the issue of if it can suck up the fungus, it can suck up the fry. Some places say a lot of water changes can shock and kill the fry and some say its good. I would like to do a lot of water changes if it will not hurt the fry.
The other big problem is what to feed and how much. Sinking food has been problamatic to find but I have made pastes that they do not seem to touch.
I have hikari first bites, kens golden pearls 5-50 micron, and frozen baby brine shrimp. I can not get any solid info on how much to feed (some say a lot so they can find it, some say a little so it doesn't foul water). All of them basically turn into a cloud in the water and do not seem to sink well (which doesn't seem good for bottom feeders). I have made thick pastes that will stay at the bottom when placed with a syringe, but they seem to ignore them.
I really don't know what I am doing here at all. Any advice would be appreciated.
This is what happened with the eggs.
A while back my albino corries layed eggs but they all fungused. I had gave up on getting them to do it again, when out of the blue they did. I was a bit unprepared. I removed some to a 10 gal on short notice. I made lots of mistakes. I used black sand and brown gravel (tried for mostly sand). The sand/gravel was dirty (came used with a tank and was dry but had dried organic matter in it). I used an emperor 280 biowheel filter for water flow (280 gph, a lot for a 10 gal which is what I wanted to keep fungus off the eggs). When they first hatched, I added about 1/6 the recommended dose of tetra contra bac (main ingredient is methelene blue). The contra back expired 15 years ago. I thought the eggs were a loss again and it was a last ditch effort (I didn't realize some already hatched). Within an hour I realized some hatched and started aggressive treatment with carbon and very frequent but very small water changes. The filter is off now.
