View Full Version : Otos and bristlenose in the same tank?

06-23-2010, 12:27 AM
I've had some bristlenose plecos for a few months now. They are fun little guys and have really changed my mind about plecos. While I really do enjoy them, I miss the cute little faces of the otos I used to have and their amazing ability to mow down algae. The bristles are decent at it but not anywhere near what I have seen in the otos. I was wondering if the two species are compatible. My initial thought is that they would be fine, but I really can't find anything to confirm or deny that.

Edit: Tank is a 30 gallon lol, oi newbie mistake

They are both peaceful fish, they will get along fine. just be sure to provide enough food for them.

Of course :) Currently three of the sides of tank have algae on them and i'll be getting fresh veggies and growing algae for them on rocks in a separate container. I also have seaweed on hand as well.

Mine must be a SS. So far mine has killed 1 3in long common Pleco. So had to buy a new one because I was holding it for a mate. Next he killed his own female. Shredded it. Also the male killed Golden Zebra Loach, ripped it apart. Next 4 Kulies. Followed by him ripping apart anything in sight that he could catch. use to watch him flare his gills. Dash around like a mad man. Similar to the people on 28 days and 28 weeks latter. But for some reason he must have been a odd male.

Thus far I have kept heaps of them, bread and sold my own stock. And never had the issue again. So could have been just that one.

On the whole I would see no issue with the Otto and BN.

Absolutly fine. I keep both together and never had a problem. Sort of like my kids.

It depends on the BN pleco. One of my BN plecos is very agressive. He's killed a rubber pleco, 3 corries, and I am pretty sure he killed the other BN pleco I put with him... He even goes after the angel fish somtimes. I have got a couple corries living with him but I don't think ottos would stand a chance.

My other BN pleco on the other hand is relativley peaceful and I think he would do well with ottos. I guess it depends on the pleco...

My male bn attacked the other male in the tank and I had to get rid of him, but he's fine with his two ladies and everyone else in the tank. I went out and bought a group of 6 otos yesterday since the store was having a "two for 1 tuesday" sale. So far the male has no interest in them. The swordtails picked on them when they were first put in, but other that no one seems to mind them. Still, I will keep an eye out for any aggression. Thanks so much everyone for your help!

Hope that they live together fine. Should be fine. Just watch in case.

My ottos were very happy racing up and down the sides of the tank and playing. Then I put in a pleco. Initially it all seemed fine but after a few weeks the ottos were constantly hiding and I hardly ever saw them. I had plenty of food in the tank in different parts of the tank but the pleco would move the food all into one area. last weekend I took the pleco out and the ottos are again racing around so I will never do that again.

If the pleco is big, it's a bad idea to mix a pleco and an otto. Although plecos are quite peaceful so it's hard to say.
