Slime Sucking Oto.

I was observing my sandy bottom fish tank and I noticed an oto pretending to suck at plants and sand. He slowly was making his way towards cory Catfish munching on some wafers. He soon wiggled into the bunch of cories and sucked onto to one of the large adult cories. he latched on just behind the dorsal fun and started sucking. the cory seemed pained by this and quickly bolted away off into the plants. the oto jumped onto a nearby plant and pretended to clean then but soon he was back on another cory sucking at it in the same spot.

is this harmful for the cories?
what can i do?

hmm if they suck on the body slime of fish then they are starving but i'm not sure what you can do since you do feed them algae wafers maybe someone who actually owns them can help you.

Are you sure it is an Oto. I only heard of CAE and SAE doing this. If he is stcking on to the Corys than it will eventually peel the slime coat away. I would seriously watch him and the Corys. Make sure you dot see serious marks. If you are feeding them properly and he is doing this I think he is a naughty Oto.

i had otos and cichlids together and once in a while i would see the oto suck on the cichlid. i assumed it was lost. i had some otos that really cleaned up, eat everything and suck on everything.

i would think the corycat could fend for itself. if the oto is doing it obsessively, maybe move it.

Ottos will do it. But like it has been mentioned It is only if there is a lack of food in the tank. I have seen my otos do it when first intoduced to a tank with Angel fish in it. Now they are in an Algea Rich enviroment.

I've also had my otos do this a couple days ago but to my asian filter shrimp. What's ironic though is my asian filter shrimp along with my RCS and CRS were al l munching on several pieces of Hikari algae pellets along with a couple other otos when 1 oto decided to suck on my asian filter shrimp. My asian filter shrimp eventually kicked him off with one of her hind legs but not before I snapped a really crappy picture of the oto doing this.


There was plenty of food laying right in front of him, so why'd he decide to suck on my poor loner asian filter shrimp?

Ottos with the munchies

Seriously though, is there any signs of trauma on your cory? Like James said, it may not be an otto.

CAEs do suck the mucous membrane but not SAEs. At least in my experience.

The pic shows an oto to be exact.

I've seen an otto or two of mine do this very occasionally; it is always right after I drop a sinking pellet and they've gotten on top of the fish that is feeding on the pellet. I think they are not necessarily trying to suck the slime coat of the fish as much as they're learning there's something edible here and how do I get to it? They are the runts of the bunch compared to cory cats and plecos and can't figure how to get to the bottom of the pile. I've never seen those same ottos do that at any other time of the day which is why I'm thinking it not a problem with them attacking and trying to actually feed on the fish itself.

I would just continue to keep watch and see if the behavior is consistent or infrequent.
