I now have my 3rd betta, dragonscale Art! He joins my veiltail Mufasa, and Halfmoon Zorro! He is in a 5.5 Gal heated tank. The filter his kit came with sucks. He didn't like it and I didn't like it either. Poor guy almost got sucked in. I will be getting the aquaclear like i have in my two 10 gallons. Those are awesome! I'm kind of tempted to return the entire kit and just buy the 10 gal for Art, but that means more money spent on decor and I rather spend the money on a filter. Do you think the filter will work different on a 5.5 gallon? It works wonders for my 10 gallons so I hope its the same! What do you guys think? Just buy a new filter? Or return the kit and buy a 10 Gal and a new filter! Decision Decisions. LOL. Here he is, Art!
