Thanks, I think I Asked you this before, should I put the odoe in with him? It would just be a bad loss if it didn't work out. I have yet to see the wolf attack anything but the worms and Rosies. I just fear I would come down in the morning with a dead pike. But I think the wolf is growing faster than the pike. Would the pike grown faster in the 75? Would it stick up for itself?What you have is likely mala. Can't really make 100% IDs in tank. But none the less likely mala.
The silver dollars should be ok. As they will get wide and big enough. Keep the mala fed.
A red wolf would be fine in a 55g for life with a very few tankmates.
