I just got a little 2" clown pleco about 4 days ago. Every time I see it, it is wagging it's tail like it cannot settle down although it seems to be eating at the same time but never on the glass. Is this a sign of stress or is it a normal eating behavior If it's normal it is the cutest fish behavior I have ever seen lol. Thanks
 
some plecos seem to do this. i dunno. my clown doesnt do this, but my L239 does. seems to be just a mannerism kind of like tapping your foot. could just be that hes still settling into the tank
 
My clown plec doesn't do that either but my BN & scribble do. Maybe it's a "guy thing", I think both of my tail waggers are male, no idea about the clown.
 
hmmm...interesting theory. my L239 i know is male...
 
I was out in the living room watching my clown plec and my bn plecs....no tail wagging by the clown, but 2 of my bn do. By the way I have never seen my clown pleco on the glass. Cleaning plants, decor and such yes, but not the glass. It also REALLY enjoys snail jello.
 
Thanks everyone that makes me feel better. It is really fun to watch though. My little ctenopoma finally decided that the tail wasn't a wiggling worm. He never bit him but would shot accross the tank thinking it was someting good until he saw it was a pleco lol. The pleco is now escavaing a little hide under some drift wood so im sure he will soon settle into the tank fine.

How would you sex a pleco it would be interesting if this is a male too. Could it be a territorial male thing, or do they release any hormones(this would be a good dispersal mechanism)? Just a thought.
 
Some plecs fight by smacking other fish, usually other plecs, with their tail. They may use them to dig spawning "nests"

Most male plecs have more bristle-like growths on their pectoral spines &/or gill covers (operculum) but it's hard to see on some especially if they're hiders. I don't know about any hormone release.
 
clown pleco behavior

At least you see your clown pleco!
My clown pleco has many hideouts in a 55 gal. tank, especially around the rockwork and behind driftwood.
These are very nice fish; I have been observing mine for over 12 years now, which places this species in the long-lived category for sure.

I've got an L340 and when my briggs snail invaded his space he slapped the snail with his tail until it moved. He kept on coming up alongside and wiggling with his tail and this effectively chased the snail.
