So to make a long story short, I currently have an (almost) empty 55g and can't decide what to put in it. I was thinking of doing shrimp, but had a couple questions about it.
1)Is a 55g too big for a shrimp only tank?
2)I am running an emperor 400 HOB on it; should I keep that and just rig some sort of intake strainer, or should i ditch it and just get a couple sponge filters?
3) Are there any smaller fish (killis, neons, etc) that would be safe to add?
