Have a Tessalata and Zebra eel that are outgrowing the 65 they're in, would a 60x18 or 60x24 be big enough if all the rock was supported above the sand allow them the entire bottom to swim around? I do have 180 reef that I could move the livestock into a different tank.Picture is the 180
Your 180 would be better. Think about their adult sizes, tessa being around 5 feet long and zebras up there as well. You shouldnt have an eel in a tank they cant stretch out to their full length and swim around in. 180 is too small long term for the tessa. Zebra alone yes 180 minimum. @HAAAAAAAA can help with the tessa, I dont have one but I do have a Zebra.
