Just had a quick question. I'm getting worried about my catfish eating my bichirs. It's a 15-16" L. pictus. I have 6 bichirs that are about 12" and a gar that's about the same. Would putting them all (the bichirs and the gar) in a 75 be too much? It wouldn't be permanent, just for awhile. Filtration is 2 x Penguin 350's and an XP3. I'm trying to figure out how to move some of my fish around.
Would you please repeat the second grade?
