2 Angel fish 3 swordtails
Platies
Gouramies
5 male guppys 8neon tetras

When ever you want. But be aware of the size of the sucker fish and how big the other 4 fish will get because if thy will get like 4" each you will need a bigger tank. And also if there is not very much algae you can just buy algae pellets from like Wal-Mart and feed those.
I am looking to get 1 or 2 BIGGER fish for my tank with the the measurements above. I am thinking maybe a shark but I dont know of any. So please post some fish that grow to about 10-16" that look cool, and would be suitable for this size tank. I am not planning on a community tank. Just 1 or 2...
