This tank is perfect for reptiles and amphibians..! It has never held fish so I am not certain if it can hold the water. I have had snakes and geckoes and it worked excellent.! The dimensions are 24x12x17 tall with a screen lid. With the stand the total dimensions are 45x25x14.5. Stand Included.! I am no longer keeping because I travel often. I have other accessories available too if you are interested in different hides, water bowls, etc.
