First Food

[mikev]

Hi,

I have four newborns who are likely Cories (eggs were removed from a community tank two days ago, 3-4mm fish hatched overnight in a container; yolk sac is still present, probably good enough for another day, fry active despite yolk sacs). Then I'll need to feed them. Is there a way to use artemia somehow (I hatch it daily for other fry)? Decap? Golden Pearls?

I had cories born before, but those made it "naturally" without me doing anything or knowing about them. I cannot return the new ones back to the tank, they will get eaten for sure.

The species involved is either C.Panda or C.Metae ... hopefully I'm correct about the fry being cories, the tank has a bunch of otos and other small fish that may lay large eggs in theory.

Thanks.

Too large. Squeeze a nice ripe sponge filter into their container. Nothing better as a first food. It's all I use for the first 4 or 5 days. Then 5-50 micron powder mixed with water and put directly in front of them with a turkey baster. After about 10 days I use the decapped eggs, depending on the specie and the size they have reached by then. As always - your mileage may vary, but it works great for me. - Frank

Hi mikev

Take Coryologist's advice on this. I start them out that way too. This is a 2 1/2 gallon tank that has had a chance to settle down a bit. You might not see the corys for a few days, but when you do you will be surprised at how much they have grown.

Thanks, will do. Actually, I found a microworms culture that is a month old but still looks healthy, I'll give them a bit of it too tomorrow.

These do look like cory egg/fry, right? (sorry for the awful quality)

Yep. Them be Corys. - F.

Thanks!
Six (all the eggs I found) hatched, the oldest look very much like cories now. They are pretty large, maybe 5-6mm after the yolk sac consumed.... danios/rainbows/gobies of this size handle artemia just fine ?


Squeezed a sponge, added small amount of microworms.

Reconfirm, if I may: bare bottom? No gravel?

(I put three small lava rock stones to provide biofilteration; nothing else in the container.)

As of yesterday morning:

Cannot give a 2.5g right now, if they make it for a week, I will give them something larger than the current 0.5L.

They seem to be doing ok, and now even active during the day (they were evening-only at the beginning). Very likely they are eating brine shrimp too, at least they chase it (I've been giving them a little of it too).

Question: catfish wafers. Needed at all? At which point? Which brand? (Sera ok?)
The preference is to avoid them until the fry is large enough for a real tank...not sure if they can be grown on brine shrimp and decap alone.

Thanks.

One more question, if you don't mind: does what you said above also apply to C.Habrosus?

(I found/removed about ten eggs in their tank yesterday... no doubts what they are, this is a single-species tank,.. if they hatch, it will be in 4-5 days...)

Thank you!
