When did you photograph this triggerfish? I can add it to Zootierliste so others know about this species in Moscow. I'm also glad to see another person with such an interest in rare fish species. I would love to get in touch.
Hi, I've got photos of this fellow from a visit in 2018 but this picture was from October 2019, no idea if it is still alive or not but it had moved tanks between those visits so it's presumably doing well. Very welcome to drop me a message!
