cory and blood worms

[Sea-agg09]

1. bloodworms are full of phosphates, and pretty high in nitrates as well. Not the best food IMO. Shrimp pellets as a primary food and an algae wafer once a week is far better.
2. Toss a air stone and see if things quit dying.

It is only the Leopard Cory that are dieing. my skunk corys are doing great. All my other fish are fine (tetras, skunk cory, amano shrimp, Discus. My levels are fine (ammonia, nitrate)

I've had this happen once or twice over the years.

Check with the lfs you got them from and see if they had problems with the remaining batch. Sounds like it could just be a bad group of fish.

Fish go through a lot between the supplier or breeder and your tank.

The rest of your fish are ok sounds like something endemic to these fish.

addition of the air stone is a good idea.

Frozen krill is another really good food. Might be too big for cories and Discus. Anybody had any luck?

Oh I did not know that haven't ever seen it in the fridge at my LFS. Gonna check around. I have the freeze dried krill and I gag and get the hibbie jibbies...............I do have my limits.

I use Tetra Freeze Dried Krill for my Frontosa colony and they love it. I used to use frozen krill but its easier to get the dried kind. Not sure if there is any difference in nutrition.

Dang man, it sounds like you might have got a batch of sick cories....
I dont know why everything else is doing fine and only the Leopards are dying...????

This happens often...some cories due fine in tall tanks...others dont. I have found that sterbai corys will die in a tall tank for the most part. Emerald coryies seem to due just fine. Just my input on tendencys I've noticed while dealing with tanks on a daily basis.
