I have a question about my common pleco I was hoping someone could help me out with it. My pleco just stays in the same spot all the time and he is getting really fat and doesnt seem to be eating. Can anyone help.

Can you answer a few questions first?

What are you water parameters? (Ammonia, nitrite, nitrate)
What's the temperature and pH of the water?
What other fish you have in there?
How big is the tank?
What are you feeding the pleco?
Any other physical symptoms besides being bloated?

im not sure what the parameters are but the temperature is about 27 degrees celceus, 20 gallan tank, with 2 red eyes, 1 bala shar, 2 guppies, they all have been in there for a year or more with no trouble. the pleco seems healthy other than being really fat and not eating. i feed the pleco algea waffers.

You should look into getting liquid test kits, preferrably the master test kits, to test for ammonia, nitrite, and nitrate. Those are vital numbers that determine the well-being of your tank.

How big is the Pleco? I hope you realize that the tank is too small for the Pleco and Bala shark, the can both get over a foot long. Bala sharks also do best in schools of at least 5, and to house a school of them, you would need a much bigger tank. I hope you plan on getting at least a 55 gallon.

As for the Pleco, it would be nice to have more information, especially your water parameters, and maybe a picture. Try cutting up some zucchini or cucumber, maybe he'll eat that.

How often do you do water changes and how much do you take out?

I will get some test kit stuff. the pleco is aboutg 3 to 4 inches long. I was planning on getting a bigger tank in the new year. I also had more bala sharks a year ago and they died and i am afriad to add new fish in the tank because i dont want to bring in disease. anyway thanks for your help and i will let you know when i get the test kits tomarrow and in the mean time i will feed him some peas if that is ok for the pleco.

2 things... I notice you said you feed the pleco algae wafers... any sign that they're "disappearing"?
Also, have you watched the pleco once the lights are out, at length? It is very possible that he is eating just fine... too good, in fact, which would cause him to get fat, and that he has a favorite spot he returns to for resting. Remember that plecos are nocturnal, and most of their activity level will happen once it's dark.
Water params will surely help.

ya i took the skin/shell of the peas first. Also I have watched him the light have been off for a few hours now and he still hasnt moved. when i feed him algea waffers the just disolve and leave stuff on the rocks in the tank he doesnt eat them, just stays in the stop and moves there a little bit. maybe he is constipated?

A lot of times plecos are just really stubborn with eating, and can be frightened very easily.

Do you have some hiding spots for him where he can feel secure?

JouteiMike has a good point. I also am curious to see the water params... if the pleco isn't feeling well because of something in the water quality, he's not going to have much of an appetite, and he could in fact be dealing with internal parasites, and water params have to be good enough before it's safe to medicate. Have you counted your other fish lately? Also, have you noticed if he's done any cleaning of the glass or rocks in the tank? Even if you don't see him, if nothing is growing in there, I'd think he's finding food at some point.
For sure get some hiding places in there, they tend to like large pieces of driftwood where they can get beneath it, but rocks stacked against each other can make nice caves too. Make sure the cave is big enough for him to get completely into it.

Bottom line.
DON'T wait until you get a test kit.
DO A WATER CHANGE!!!!! Do it now!!! :D
Yup, get off the computer, and grab a bucket and some dechlor! :p
30% if you have done a water change in the last month.
50% if you have done a water change in the last two weeks.
80% or more if you have done a water change in the past week.

The different percentages are to ensure that you don't shock your fish with a huge pH drop while still giving them the benefit of a water change.

Just about 95% of all lethargy and bloating problems that arise with tanks such as yours...(fish too large for the tank that have been in these conditions for 6 months or more) can be alleviated with multiple water changes and RELIGIOUS water testing for nitrATE levels thereafter.

As for the bloating. Stop feeding for a couple of days or even longer.

GET A TEST KIT.
:shock: :shock: Yup. Get in the car, go get one now, tell your spouse you're off to get a pack of smokes or the new PS3 and go grab a test kit. No strips though. You need the liquid nitrate test in the WORST way. :redyay:
Good luck!
