I have a 10-gal that is "supposed" to be my hospital tank, but I'm tired of looking at it empty. I have extra plastic buckets and totes that can be a hospital tank if I ever need one. I'm thinking to get a betta for this 10gal aquarium. It'll have a sponge filter, gravel bottom probably, and a few vertical-stem type live plants such as Java Fern. What else does a betta need? I see things online like betta leaves - are these necessary? They say they are for the betta to rest - what are other things like that different for bettas than other fish? I plan on tossing a couple nerite snails in with him.... I know they live a solitary life, but in a 10-gal could he also have a handful tiny, non-bright, non-pretty fin fish friends? I have a divider I could throw in if it became a problem. Thoughts on doing a blackwater or otherwise high-tannin tank with a betta? Yes? No? The aquarium shop I'm buying my betta from doesn't store their bettas in cups - each has their own 1-2 gal bowl in the shop - so I'm glad to give them my business, but they didn't have a lot of additional information when I asked. They also have a LOT of tail type varieties and colors that you don't see in big box pet stores.
