Good evening!
I have a group of 8 panda corys in my community tank. I acquired them at two separate times. 4 of them I got four months ago and the other 4 I got about 3 months ago. Both times they came in at the same size which was quite small.
Now I have 4 large corys and 4 that are not much bigger than when I first got them. I treated all of them with the med trio when I got them but is it possible that a parasite has snuck through? Their eating behavior looks normal they just aren't growing as fast as I feel like they should be. I feed krill flake, fry food, frozen bloodworms, daphnia, and baby brine shrimp as well has algae wafers.
Any advice would be greatly appreciated. Thank you!
