I'm on the hunt for a 20 gallon long bare tank, to grow plants in the garage. It doesnt have to be pretty, just hold water. Also open to other sizes if price is right.
Let me check, I believe I still have a 29 gallon under my 125 ( it came from fishguy1978 years back) it is painted blue on the back if I remember correctly. I used it for crayfish to feed my puffer but shut that tank down a year back or so.
If I have it, it’s yours if you want it…. I will check later when I’m home.
