Now, I don't actually expect anyone to ID this. But last week I noticed a baby fish swimming in the refugium chamber of my sump. For reference, this is a fairly new Cobalt C-vue 40 with the built-in chambers and filter socks .My best guess is that this somehow came in the macros, which have been present since March-April. Otherwise, is it possibly from the firefish? I've only seen this one. It's about the size of a guppy, and color-wise, could be anything. Shows grey-brown right now. I have to assume it's likely a common captive-bred/tank raised type of fish. At what point would you try and capture/move something like this into the display? I think it should stay a little while and obviously the refugium is probably the best area for food sources currently.View attachment 5151Picture is pretty crummy, but it's the best I could do. It disappears easily and for days at a time .
