Hello all. This is my first post, so I'm not sure who all will see this but I'm looking for some help. I recently purchased a used 10 gallon tank to add to our growing collection. I want to put this one in our living room, but I don't want to put a lot of money into it. I have gravel, a filter, a heater, an overhead light and one medium sized decoration. Are there any tropical fish that don't require lots of plants or many places to hide? I'm looking to get maybe 5 or 6 fish. I want something lively and fun to watch. Maybe tiger barbs? I dont know a whole lot about those though. But any fish really would be fine with me as long as it is active. I'm not opposed to putting maybe $15 into the tank other than fish, but not a whole lot more than that. (only reason for that is we just got a 60 gallon as well and I want to deck that one out.) thanks for any and all help!!
