La La was not always this color, I got him at the local petsmart. He was sort of pale almost teal but not so much blue. When I took him home I notice he had little pin hole in his tail fin that quickly healed. his face darkened and his blue color started to really show. He looked like a totally different fish.
I am having a bit of trouble with him though. You see La La really likes swimming in the filter current for some reason. He has a whole 20 gallon tank to himself but keeps swimming in the current. I noticed a small tear on his tail so I found a temporary solution by blocking his way to the filter by dividing the tank with canvas screen. I might have to down grade him to a 5 gallon with a sponge filter and keep the 20 for other fish.
What do you all think? Will down grading stress him out much? Is the current for a sponge filter for a 5 gallon gonna really make the difference?
