I had some clowns in the past, and they would sometimes make clicking noises. I am not sure what it meant, but it was interesting to listen to. They seemed to be happy, so I think it wasn't a negative sign.
If they get too big, eventually I'll have to sell them.
I was vacumming yesterday and I found some empty snail shells. I was thinking, good boys.
They stick their head so far into the gravel to find things, they're funny! He'll dig his head down deep in there and I'll start to hear clicking like he found what he wanted.
A 3" hole goes through the 8" wide driftwood from one side to the other and there is a small hallow spot inside of it. Honestly I'm not sure why it hides in there by itself instead of with the other clown loaches.
