Banded cat shark

Created on 2017-07-31 by Asianreefkeeper

Alright so straight up. I need to move a banded cat shark into my 220. While a 380 cycles for that shark. (I’m cycling it for 2 months because of the waste sharks produce) The problem is that there are small fish, crabs, and snails in that tank. I’m planning on getting it at 4-6 inches. At a size that small should I be worried of keeping it in there for a month? Thanks! Read more »
