I've had him for just under a week, and he seems to be doing really well. His colours are popping, he eats well and seems pretty content in his heated, filtered and cycled 4.5 gallon tank. Water levels are coming up constantly clear, he's got a well stocked, big clean tank with tons of hiding places, plants and a few ghost shrimp to bully.
I've noticed that towards late afternoon and evening in particular, he begins to pace one side of the tank, with his nose to the glass. He swims up and down and then from edge to edge of that one side over and over and over for up to an hour at a time, then taking a break and inspecting all his plants before going back to it.. I can't figure out if he's seeing his reflection and is chasing it, if he gets bored towards the end of the day, or if he's just a bit of a weirdo.
Thanks in advance.
