JohnT Posted March 24, 2021 Share Posted March 24, 2021 I got a second hand fish tank last weekend and it came with two fishes, a pleco of about 4" and a Oscar of about 2". I'm worried because I don't see the pleco moving around during the day and for the past two days he has been on the same corner of the tank! "He" just alternate between the floor and one of the sides of the tank. I've been feeding him but I'm not sure if he's eating the Algae Disks or they are just dissolving. I tried giving a piece of cucumber but it didn't work. So, my question really is how do I know he's well? Link to comment Share on other sites More sharing options...
gardenman Posted March 24, 2021 Share Posted March 24, 2021 Plecos are pretty tough little fish. You can pretty much assume he's well until proven otherwise. Put some food in just before the lights go off and chances are it'll be gone in the morning. 1 Link to comment Share on other sites More sharing options...
Hobbit Posted March 24, 2021 Share Posted March 24, 2021 Depending on the color of your pleco, you may be able to see whether his intestines are full when he’s on the glass. Here’s a picture of mine—note the brown intestines. 😄 3 1 Link to comment Share on other sites More sharing options...

I wasn't sure if it was a good indication or not. 1 Link to comment Share on other sites More sharing options...
Colu Posted March 24, 2021 Share Posted March 24, 2021 (edited) What type of pleco is it? You could add some cave for him so he feels more secure try feeding spinach or blanched lettuce and cucumber previous owner might have never feed it vegetables you might have to offer it couple of times before he eats them Edited March 24, 2021 by Colu 1 Link to comment Share on other sites More sharing options...
seakitty Posted March 24, 2021 Share Posted March 24, 2021 My pleco seems to eat more at night after lights out. Her tank mates eat all their flakes and then go after her wafers. She has learned to chase them off her food and I was noticing just this morning that her little tummy is growing and yes I can see the brownish colored intestines because she is a pale yellow color. Thank you @Hobbitfor that info because when I first started noticing that I was worried that something was wrong with her. All that being said my pleco hides in the driftwood or her little cave during a lot of the day. 2 Link to comment Share on other sites More sharing options...
Hobbit Posted March 24, 2021 Share Posted March 24, 2021 @seakitty @H.K.Luterman You’re welcome! I have to chuckle because what we’re seeing is literally poop—if they sit still you can even watch some of it get pooped out. 😆 Gross, but definitely normal. 2 Link to comment Share on other sites More sharing options...
JohnT Posted March 24, 2021 Author Share Posted March 24, 2021 Wow, thank you so much for all the answers! Unfortunately my pleco is on the back of the tank - his belly is facing a wall and it's quite hard to move the tank around.. so I can't see his internals right now 🙂 I'll try to feed him some spinach - how do you sink them? To the best of my knowledge he's a Plecostomus, and that's all I know 🙂 Link to comment Share on other sites More sharing options...

Alternately, stabbing a fork through it, and then submerging it fork and all will make it sink.

To the best of my knowledge he's a Plecostomus, and that's all I know 🙂 It's good to know if the Plecostomus you have is a dwarf or the COMMON Pleco, quite a few are re-homed because the previous owner finally realizes that they can grow to over a foot long and their tanks will not support them. Common Pleco's need a huge tank 75-150 gallons, otherwise they will become stunted in their organs and not thrive. Have you tried blanched or frozen sliced Zucchini, mine seem to prefer it over cucumber. Link to comment Share on other sites More sharing options...
FrozenFins Posted March 25, 2021 Share Posted March 25, 2021 When I first got my bristlenose pleco I didn't see him for like the first month. The I saw him maybe, once a week. He used to never eat any of the algae wafers, and would never come out during feeding. After a good 6 months, he eats with all the other fish, I see him a few times a day, and wont scurry away so fast when he does see me. I wouldn't be worried. Give him time to settle in, give him LOTS of time. and Yes defentley try what @Trish mentioned, FEED THEM VEGGIES. They LOVE those. 1 Link to comment Share on other sites More sharing options...
Tanked Posted March 26, 2021 Share Posted March 26, 2021 A change in behavior is usually the first indicator of a problem. Having just gotten your pleco, anything is possible. Give him some place to hide. My Plecos have always preferred enclosed spaces. A piece of PVC pipe will work short term. If he is foraging, he will find it. 1 Link to comment Share on other sites More sharing options...
