So he got a tank switch today. His swimming problems made it hard for him to swim around in the 2.5 gallon and he had a hard time with the filter.
And I have been wanting to give Vespasian a slightly bigger tank than his 2 gallon and having short fins made him fine with current.
So now Vespasian is in the 2.5 gallon and Caracalla is now in Vespasian's old 2 gallon filterless tank. I also gave his different sized plants so he can perch where he wants. :)
Here is Vespasian enjoying Caracalla's original tank:

Here is Caracalla's new home:

And some more close ups of him:
