I swop and change fish (well, some of them). Lucky to have an LFS
that does it willingly as long as I keep buying the latest fish I am into from their store.
Here's a photo of each type of fish I am keeping in my tanks at the moment. I have three active tanks at the moment, five are in storage... lol
Peacock Eel (was sold to me as a Tiretrack Eel, but I think he's a Peacock).
Tiger Barb (large school, almost a species tank if you don't count the CLs!)
Limit of 4 photos per post, so see below for the fish in my third tank...
