I have a 90 gallon acrylic tank you can have for free. It has a crack in the top rim which is why can no longer be used as an aquarium but would be excellent for a reptile cage. It is reef ready with a blue back. I also have not cleaned it from when it was drained so there is algae growth on the sides. I am told that it comes off easily with vinegar but I haven't tried yet. I can send pictures if you send me your email address.
