Hey guys, i had a red zebra in my tank the other day and he's been missing for a few days now. He was about 3 inches, too big to be eaten by my other fish... My tank just cleared up from re-decorating and i don't want to mess things up trying to find him. Will he become plant food if hes dead somewhere or will it be a major problem? 100 gallon tank with cascade 1500 canister filter live sand and 22 fish...
