I had two betta fish, Peanut Butter and Jelly, until recently, when Jelly passed away. I'm pretty sure he was overfed. He got very bloated and passed a short time later.
Here's my question: I want to swap tanks. Peanut Butter has a tank with a very crappy heater and a lousy filter, so I want to set up Jelly's old tank and put Peanut Butter in it. Jelly had the better heater and I'd like to get a better filter. What's the best way to clean up Jelly's tank, gravel, and plants to make a better habitat for Peanut Butter? I don't want to clean it with anything that may harm him and I want to make sure the tank is clean and ready for him before I put him in.
It's a small tank, only 2 1/2 gallons, but I live in a small apartment and that's just about all we can manage.
Also, can anybody recommend a good filter for a small tank like that? I have a Whisper mini thing, but it kind of sucks. It keeps falling off the suction cups and it clogs if you look at it too hard. I'm very unhappy with it and Peanut Butter deserves something better.
Thanks for your attention. I really relied on this site when Peanut Butter was ill last year, and you guys were very helpful.
