I'm still not sure how to care for these little fellas, & I have seven of them. Are they freshwater or saltwater animals? I know they go well with Hair Grass, so I got them some. I got them some snail food, one kind of which they seem to like, & the other, which they do not. They do not really seem compatible with the Globe Waterfall tank I got them, so I'm getting a slightly larger tank with a filter & a cover. Hopefully, they will feel more at home there. I've treated their water the same as I have the freshwater betta tank, but their water is very cloudy & smelly. They are smelly little guys. What little I've been able to find online only tells me that they need a filtered tank, same as the fish, & warm temps. Is there anything I should be doing for them that I'm not doing? I've given them some large quartz rocks to climb on, which they seem to like, except that, right now, the tank they're in is too 'stormy' for them to do much climbing.
