Ok, so I got a 20H aquarium and an aquaclear30 filter and I had a few tank stocking ideas such as dwarf rainbows with some other fish and snails or a betta and other fish and/or shrimp, and my other idea is dwarf gouramis. By the way the comma means that its the end if the stocking suggestion and I know I cant have all those fish in a 20H. But I would like to know some ideas possibly and be able to start a lovely aquarium. One other question as well... Do you all think an aquaclear 30 is good enough for my needs or should I get a seachem or aquaclear 50?
