Yes, that's what I meant. My brain mixes them up with African dwarf frogs for some reason. They're very cute. There's a gal that breeds them locally and I've seen her setups and just loved them and their singing is so neat. They're really interesting little creatures, but I think I'll just check out her pics on Facebook and save myself the work.
I won't reuse the old ones for this. I'm planning to use distilled water in here and lightly fertilize, and since I have no idea what my husband has used them for in the past, probably Round Up, it's not worth the risk.
