ok so im am starting to fall in love with the wolf fish (the mean face and teeth), but i have a standard 60g, and it seems that the red/rainbow is the right fit for me. but quick ? is the red very difficult to care for, easy to wean onto pellets(hikari), possible at all with tankmates that are too big to eat(serverum, silver aro), average price, difficult to find, anything else i should know
