Well, he's back to his wiggly self today, staring at me and begging for food. I've had him four months. Yesterday I couldn't even take a close look, he would dart away to the back behind the plants, and he spent a good amount of time inside the cave. I did add the last of my Sresscoat last night, I'll have to get some more.
I suppose he could have ran into that fake rock, or into a Cory. I've never seen him that clumsy though. That would be great if that was all it was, as long as it heals. I don't really like that rock anyway, I'm thinking of getting some Anubias on driftwood from AquariumPlants.com to put in it's place.
Thanks everyone for the input so far. If anyone else has any ideas, feel free to pipe up.
Wouldn't you like to beside the seaside?
