Shredded Guppy Tail
My male guppy has a shredded tail and crooked back. He swims but it looks like a struggle. He is kept in a 40-gal with 2 pearl gouramis, 3 female guppies, 3 julii cories, a dozen cardinal tetras and a half-dozen amano shrimp. I'm assuming someone is harrassing him although I've never seen it. Everyone else is in perfect shape and coloring.
I just moved him to a 20-gal tank that is currently plants only (plan on adding red cherry shrimp, and maybe some SAE's). I fed him blood worms and he gobbled them down. Will his tail grow back? Is there anything I should do to hellp him recover?
