Hi everyone! I haven't been around much, but I have some questions for you. Long story almost short, I keep fish and my coworkers at my salon got excited by my fish keeping and wanted one as our work pet (we are open 7 days a week :). We've had our betta since March, his name is Snip, he's been in a 2.5ish gallon heated jar with a sponge filter and a couple live plants. Earlier at petsmart I picked up a minibow 2.5 for him on clearance for $15 from $40 because it was missing the filter cartridge. I just put it together, I think I'm going to cut out a piece of foam from one of my cycled tanks and put it in the cartridge spot. Does anyone use this tank, and how is the filter? Do you use their cartridge or your own material? Do you baffle it, and if so how? I'm going to set him all up and probably move him Friday.
