I now have a 50 watt heater and a divider for the tank. I won't split it up yet since I still have 3 oto cats in there. Once they are put into the 45 gallon I'm setting up I'll divide it and add in Hannibal. He should be a good size by then and won't get lost in his 5 gallon half.
I've divided my 10 gallon now and once I get the heater working I will put Hannibal in. Mushu should hopefully follow in a few days. The three oto cats will stay on the half with the filter because they love to hang around there.
I've also started to set up a 45 gallon with my dad. The under gravel filter and the gravel itself are ready to go.
