I drew a fish but I couldn't find it anywhere when it switched to the tank. Perhaps you could highlight the user's own fish, at least initially?

EDIT: Tried again and now I see there is a highlight, but it's pretty hard to see a in a busy tank, the color contrast is not very high

There are light yellow rays coming out of your particular fish

I noticed that on the second time but it’s still not very easy to see against the light background

Same I drew a mola mola, maybe the probably filtered it out (not fish enough)

Took me a sec but your fish has a yellow "glow" effect around it

Mine was highlighted with golden rays around it (like a cartoon sun)
