I just got a 55g using rena filstar xp2 and rena 200w heater. I'm planning on getting a pair of firemouths that i found an excelent deal on. They are about 4-5 in. I was wondering would i be able to put a 2 in. salvini in the tank as well or will the FMs terrorize him? I've read taht salvini's are pretty aggressive even at a small size. I would also like to eventually add an EBJD when I find one in stock for the right price. I had 4 juvies but sadly they all past while I was on my honeymoon. I had a friend feeding them and due to a HOB filter and cheapo heater malfunction in my old 37g tank they all died. So I'm starting off fresh with a bigger tank and better filter and heater.
