Hello, I got 8 20 gallon tanks for sale. 4 with siliconed dividers and 4 without. All have been plumbed with fixtures already included. You can cap off and use normally or run them in a system. They need to be cleaned and most of them already have gravel. Picked them up from a shop that was closing. Selling them for what I got into them. $25 each Any questions please feel free to ask.
