Biotoper said:Yeah, a densely planted filterless 5g tank will be lot more work to set-up (light, substrate, CO2 maybe) than one w/ sponge filter and w/o plants.
Also, I'm sure everyone knows, but I'd just like to clarify that we're talking about Betta splendens. I think most other Betta species, like B. imbellis which you occasionally see for sale, need bigger tanks.
You can go no or low tech and have to worry about the light only (2wpg), substrate would only need to be sutible for low-light plants...
