Hi everyone. I'm thinking about setting up a 30-40 gallon FOWLR aquarium over the summer. Not really sure what I want to stock it with yet but the ideal would be smaller hardy species that are not too aggressive. The reason I'm here is because I was wondering if there are any good native species for this setup. I've been looking escpecially at the idea of keeping a small school of either Rainwater Killifish or Sheepshead Minnows with some kind of tropical Goby or Blenny.
So main question is does anybody have any experience with a setup like this? I've been researching Sheepsheads and it seems like they might be to agressive for it.
I unfortunately had a tank collapse last year, but until that point I kept a 90g marine tank of natives. I agree with kanus on the sheepshead minnows, they are mean towards each other, but I've never had problems with them otherwise. My favorites have always been blennies, specifically crested blennies. They too may chase conspecifics, but nothing violent, and no aggressiveness to other species. Pipefishes would be hard to feed and are outside of my aquarist abilities, but you probably know more than me!
Currently I keep a small brackish tank with rainwater killifish, a freshwater goby, and a spinycheek sleeper. The sleeper is my favorite, but I have to keep him very well fed or he will eat anything that moves.
