We recently set up a 29 gal tank with some tetras and a peacock eel. It is a planted tank or at least aspires to be. We bought a bristnose to help with algae that was growing everywhere over night. He did an amazing job and cleaned the entire tank in a couple of days - he's a baby and was only an inch long when we brought him home.
Well now he's eaten all of the chlorophyll off of the four sword something or other adult plants in the tank. I had been putting romaine lettuce weighed down by some drift wood, but he continues to eat both the lettuce and the plants. Please help - are bristlenoses not compatible with aquatic plants? I did not expect him to devour them. Intact I notice new Alger patches on the glass because he is too busy getting every last green spot on the plants. Can I not have both?

Well Pleco's are not relatively good algae eaters. But the Bristlenose will eat some when it is young but when he gets older he will stop. I mean some will not even touch algae. Secondly is your tank cycled. And that is weird he is eating your plants. Make sure he is well fed feed him vegetables and algae wafers. Maybe he will stop. Also add some driftwood. Good luck with the plants. It is odd that a BN would eat plants, I have never heard of it. Are your plants dying? The only reason I say that is, he might eat the dead decaying plant matter.

My cycled tank has driftwood and vegetables. The plants were super healthy. Everything I read said bristlenoses were great for controlling algae in a small tank :(. I guess I should get rid of him if he's not going to keep up with the algae consumption and is eating my once beautiful healthy plants...

BN are good fish but not really algae eaters. Give him Zucchini and I bet he calms down peas (cooked/broken) will help, too. Alage wafers will also help. :11:

First of is it a bristle nose? There are hundreds of species of sucker mouth catfish. second is it wild caught or captive bred?
Wild caught catfish are often starving when they arrive in the dealers tanks, the best way to tell if its starving is sunken eye sockets and overall thin apearence.
Do look/treat for parasites, maybe that's whats causing the fish to eat your plants its simply not getting the algae/food it needs because its got parasites.

As others have said, give him something besides what he can find in the tank for himself to eat. Seeing as he is new, he's prolly just starving - how fast he cleaned up your tank is a sign of this, I think. He's run out of algae and must find something else to eat if you are not feeding him.
He's a growing wee fish so give him some wood to chew on and a nice piece of zucchini every night or every other night, and he should leave your plants alone.

The store said he was a bristlenoses, I don't know the source. He has wood and veggies, which he eats, but he's still on the plants. Maybe he does have parasites...
Any recommendations on a great algae eater who will eat the algae off the glass and plants, but not eat he plants?

Thank you for help so far :)

IMO there's nothing better than a nice school of otos for algae clean up and being cute little beggars to boot.

Bristlenose will rasp rather harshly, particularly on the wider leafed plants such as amazon swords. You won't find chunks gone, but rather the leaves will become thinned, almost see-through, and then they will get that "tattered" look.

A better but also smaller pleco for planted tanks is the bulldog pleco, also call rubberlip pleco. They are much gentler.

I'll echo zucchini - I also give my shrimp pellets and algae wafers... The shrimp pellets they LOVE!! They flock to them immediately... :) IDK if it will keep them off your plants but it's worth a try :11:

I recommend nerite snails. The females do have a nasty habit of laying little white eggs everywhere, but at least they don't hatch.

First thing is that the best way to get rid of algea is to look at what's making it grow in the first place! :ssmile: If its green algea, have a look at where the tank is placed. Is it near a window that gets direct sunlight? If it is then move it, if you can, or try and limit the light somehow. How long do you have the light on on the tank for? There's no need for the light to be on all day and half the night. Put the light on when you're watching the fish, then turn it off. Basically if green things are growing, then there's plenty of light so you can afford to limit it.

Second thing is that YOU might just have to give the BN a bit of a hand to clean up the tank every now and then.

Third thing is what kind of tetras and other fishes do you have? Some of those could be the ones trashing your plants. :ssmile:

Most algae is caused by too much phosphate and/or other imbalance. Nitrates being too high (or near zero) can also be an issue in a planted tank. Large water changes and proper feeding of plants combined with correct color/time of lighting and if mod/high lighting, CO2 can control algae. Or, as I tell every one, get an in tank algae scrubber and feed the plants carefully.
