Got a new aquarium that I'm almost finished setting up.
For $50 I was able to get a heated 55 gallon aquarium, wire lid and light.
Added some gravel, starts for live plants, a dozen crayfish, some mosquito fish, 2 sunfish, a rio grande cichlid and a pleco.
You can see one of the sunfish, the big crayfish and the pleco in this picture.
I also built a large canister filter with an aerator exit today. So far it has been working.
