Fish Crazy
Thats my current set up for my fish.. i plan to buy a new tank soon within a few days
these are the stuff im going to buy:
1- 10 gallon glass tank (13.99 at petsmart)
2- Sponge Filter(of the materials for it using instructions from DIY Section)(Assume $5 at most)
3- Air Pump to operate sponge filter($10)
4- 25 Watt Heater($20)
5- Hood For tank, with custom built lighting(not sure for that but need ot get a hood, then decide on the type of lighting)(not sure will assume $20)
Total Costs are:
14+5+10+20+20= $69, but i will buy the parts steadily but things will buy for sure are the tank filter and air pump, the other materials i will purchase when the time comes.
Oh yeah note: the Betta's green parts are actually light blue
And hes stunning 
To be honest, not a lot of things can be kept with betta and the only other catfish thing I can think of are otos, and they eat algae - plus they're not even catfish. If you think you can maintain good water quality and put sand in there, fine. Also, Cories love caves. I suppose it's not a must, but mine always like playing in the wisteria, and I love to see them showing their true nature.
