This will be my third tank setup......
The first one is 20 gallons, houses a rather large bala shark, a rather large iridescent shark, two rather large catfish *but not your regular ones, these are like 10 cms, silver with black spots and long long long whiskers, two swordtails, two Cullys, a tiger barb or barb tiger or whatever and one of those things that eat off the glass....
The second one is 10 gallons, houses 6 large pearl gouramis, 2 catfish, a tiger barb (whom I had to relocate because he attacks my iridescent shark) and again, one of those that stick to the glass to eat....
I would like to get creative with the third tank though
