I have 3 Madtoms 3-4 inch that I'd like to relocate into a tank with a variety of sunfish including longear, pumpkinseed, and dollar.
I have kept them with a few juvenile longear sunfish, one inch or less, for short periods with no problem. In this tank I have larger sunfish in the 3-4 inch range. Assuming sufficient space for the bio-load and also tons of hiding spots, could their spines potentially injure my sunfish if they got curious or during feeding?
Also wondering how much they dig. They look like they can get kind of aggressive messing around the bottom looking for food or being curious. The tank they are in now is not planted but the one I am considering moving them into is dirted capped with 1-3 inches of rock/gravel and has lots of plants so digging could turn it into a mess.
Thanks
