I have been feeding colorbits to my cardinals for the past few years and I wonder if there are any other good food for them. They are so tiny and I have to crush the colorbits into powder in order for them to fit in the mouth specially for the baby cardinals.

The Hikari micro pellet looks good. Here is a link to it:

Those are the exact pellet I feed my tropicals, I've been feeding it for about a year and my fish are healthy.
They also like bloodworms and spirulina flakes

Thanks for the reply. I will go grab a bag on my way home tonight.

The one problem I could see with the micro pellets is they will sink when the water gets agitated, and tetras don't like to eat food that hits the bottom of the tank. Size wise it is perfect for them, but if you don't have a scavenger that looks for food at the bottom of the tank, you may have more waste problems with this food.

Should I get some cory catfish?

I use the Hikari pellets linked to above. They're described as 'semi-floating' and stays on the surface of the water for a fair while - if you feed really tiny amounts at a time, they should be able to get it all before it starts sinking.

I do have a couple of bottom feeders to get any scraps. But I try not to feed too much for there to be any.

If your tank has capacity for another few fish (corys prefer to be in groups) they'd be a lovely addition but not wholly necessary just for getting rid of waste food, as they'll only create more mess themselves, IMO.

I agree with Iclayton. I feed the micro pellets in small amounts (a little goes a loooong way) and they float then sink slowly, the tetras usually snag them on the way down.

As for the cories, they're never a bad idea ...yes, I love them so I'm biased!

I'm not a big fan of red eye fish, specially its body is in white creamy color with whiskers. But if they do help clean the gravel for me, then I might add couple in it. The main problem of my tank is all the cardinals are hiding. I probably get some zebras and guppies too.

You don't have to get red eyed, white cories you know--they come in many different varieties! Here's a link to some of them with pix.

I highly reccommend cories, too. They are very peaceful with cute little mannerisms.

i feed mine some hikari frozen daphnia from time to time.

Do cories eat fish waste and algae too?

Not algae, I had a tank that was overrun with green algae and my 4 cories didn't seem to care

Cories like algae wafers, though--go figure!

No, they don't eat fish waste, either. They need their own sinking pellet food, not just leftovers cause it might not be enough.
