William, my geriatric (almost 5 year old) betta in his cozy 2.5g home. I have dwarf hairgrass and cyperus helferi, am using 6500k 15w lighting w/10 hr light cycles, and supplement with flourish/flourish excel. Thinking about doing DIY co2, but I think I will move to a bigger tank (10-15g) with that and keep this as a hospital tank.
Here's my tank. Using crap fluval 88 CO2 kit, T5 HO light, and fluval 306 3 stage canister. Im about get huge CO2 tank from the welding store, because fluval 88 CO2 tanks are small and doesn't last long. The driftwood is cyress wood I found in the bayou. It's clean, boiled, and free lol.
