My love for fish is spreading, my 55 gallon salt is pushing me to want to get a fresh water. But with only enough space to get a 30 gallon, I am wondering if there are any easy maitanance monsters that will be able to live in it. I am not sure of the dimensions of it because I still haven bought it yet, but it is a normal shape... Are there any monsters to get along with other monsters, I would be looking for a couple fish to put in the tank and not just cater to one big one. Any info would be greatly appreciated... Or even if you don't know of any monsters, are there any spectacular fish that you guys like besides the plan old gold fish?
