I got a 10gal tank and a divider. My 2 boys will be able to see each other. My concern is if they see each other will they flare to much ? I really need advice. Will 1 50 watt heater and 1 filter do both sides ok? I may have to leave the filter off because they did not like the filter in their 3 gal tank. This is ok right? I will be doing my water changes. Just trying to make them happy...
