I'm new here :) I'm not sure if this is in the right forum, so feel free to move it if I was mistaken!
I was hoping I could get some light shed on a little problem I'm having. About a month ago I thought one of my Neon Tetras went missing. I had 5, and two died quite awhile back... so I was SURE I had three left, but I can't be certain. I only have two now. I thought perhaps it had died and gotten eaten or something, as that happened to me once a long time ago (I caught the other fish doing it! Gross)
Anyways, NOW, I just fed my fish to discover that my largest (or second largest - I can't be sure without both of them in there to tell!) has disappeared. He was a Danio. I haven't looked at the aquarium in about 2 days, as I wasn't home, but I'm sure he was there on the weekend. I flipped over all my ornaments to make sure he didn't die and get stuck, and he has definitely vanished into thin air.
I have an algae eater an aquarium store sold me when I had an algae problem - I've since moved, and no longer have that problem with the new location for my aquarium, but I do feed him algae pucks. Is it possible he's eating my fish??? I don't think any of the other fish are big enough to have attacked the danio!!
In addition to the neon tetras, danios, and algae eater I have a few bleeding heart tetras and zebra fish.
