Who Gives A Fish Forums

I've been using black sand in my 5-gallon. It looks sleek, and my betta seems to like it. No plants, just a simple setup with a hang-on-back filter. Easy to maintain, and the fish is happy.

Any thoughts on Pearlweed? I've seen it in high-tech tanks but not sure if it's worth the hassle.

Looks like fin rot to me. What size tank is he in, and did you cycle it before adding him? What are your parameters - ammonia, nitrite, nitrate, and pH?

Did you properly cycle the tank before introducing your betta, and are you soaking the bloodworms before feeding them to him?
