My son got a 2.5 gallon betta tank as a gift so we bought him a male betta which we've had for a while. We decided to get a 30 gallon tank when we finished our basement. We have it set up and it's been running for a few weeks. (has filter and heater). Currently we're trying to decide what kind of fish to get and how many. I really like the Molly's (black, cremecicle and the dalmations) and I also like the dwarf Gourami's and Red Wag Platy's and Glofish. Of course I wouldn't put that many in one tank but I'm having trouble deciding which to get and how many of each to make them happiest. If anyone has any insight I'd appreciate it. Our Betta is doing so well and my son loves him I want to make sure the new fish do just as well.
