He was being kept in a 20 from the prev owner... so I think that he's got a better life noting that they had him for 3 years in that tank!
AS far as diameter- From left to right he's 4"- from head start of shell to tail end of shell he's about 6"-
Him being in this tank for 2 months is not going to hurt him what so ever. So it's adequate enough.
If it's such an issue, I'll put him in the koi tank so that he can swim around for a few hours. Unless 1500 gallons isn't enough?
