I've had my warmouth with some silver dollars for awhile now, to see if they might be a viable combination. I wanted something reasonably active that he wouldn't be able to swallow, and it worked just fine for awhile, but he apparently keeps seeing their shininess out of the corner of his eye and mistaking them for food. Normally that's fine, they shoot away unharmed, but lately his reflexes have developed enough that he can grab them.
I now have two fewer silver dollars. Both had warmouth-sized bite marks on them, areas where scales had been scraped away, and the most recent one (just found it) looks like he bit it a couple of times. Clearly he can't fit them down his throat, but he's tried. I'll be getting rid of the remaining ones, clearly, but does anyone think this might work out with larger dollars? I doubt he'd try to eat one that was nearly his own size, and they seem like they'd be durable enough to stand up to a quick nip. The ones I have now are something like 2", he's about 4" and growing fast. Or will dollars just not work with this guy?
