Look out world; I have a spare tank. My man's sister wanted to get rid of her goldfish and pleco. We got them, and the 45g-long tank they were in, with a really nice handmade oak stand! I also got a big Whisper filter along with it, and I added it to my GFish tank.
I put the GF in my GF tank, and the pleco went in our 125g Oscar tank... and presto, a new spare tank was born.
What am I going to do, you ask? I am toying with the idea of getting a blood python. I still am not sure though; I could just upgrade my female BP into it, but it would be huge for her. I could do the "smart" thing and leave it in storage til she gets bigger, but WHAT kind of herper LETS an empty tank languish in the basement....?
