I have my lilie tank in the gh with a few fantail goldies. I tried to put a betta in there and it kept jumping out. Brought him inside and he's in a 45 gallon tall all to himself, very happy. I just wanted something in there for mosquitos during the fall. All the fantails are very happy.
Then I have a 55 gallon set up in my bedroom with Shubunkins, from late last years spawn. They were so cute, I brought about 6 inside to watch grow through the winter.
Here is what I have had set up though in the past:
55 gallon with Chiclids
33 gallon long under the 55 gallon with metal stand with baby chiclids in it.
Another 55 gallon w/wood cabinet that had tin foils and such in it.
45 gallon tall with various fish
40 gallon tank in daughters room with whatever in it...(it was taken out in dec, the filter clogged and the water ran out and to the carpet and to the padding. Had to rip out the carpet. Have yet to set it back up. I'm going to have to replace the tank, because dh left it on the deck next to the house and the water froze and busted the bottom....arrrrg!
I have several 20 gallons, then I have a little long tank with deviders for a breeder tank. I also have many 10 gallons that are empty.
Oh, almost forgot the hexogon tank we had for awhile. It was my mil's, it had a leak and we fixed it and kept a couple of orandas in it. It was a 45 gallon. We ran out of room, and gave it back to her.
