Frosty.R Posted January 26, 2021 Share Posted January 26, 2021 Hello all, Recently my Three Bristlenose have turned into absolute nightmares and bullying any fish that go near them plus they are constantly ripping up my plants. My tank stock that is Neon Tetras, Glowlight Tetras, Bolivian Rans and my catfish has always been great and friendly plus my tanks parameters are always spot on - Ph - 7.5 Ammonia - 0ppm Nitrite - 0ppm Nitrate - 20ppm KH - 6dkh Gh - 5 drops 89.5ppm (soft water) The only thing that has changed within the last 4 weeks is frozen blood worms that I have included with their varied diet. Could the blood worms be making them aggressive? My other fish are all normal...ish Any suggestions would be appreciated 👌 Link to comment Share on other sites More sharing options...
FrozenFins Posted January 27, 2021 Share Posted January 27, 2021 I'm wondering if the high protein foods has made them want to breed. I am no expert on breeding fish, but it would explain why there more aggressive. Have you seen any eggs? Look inside their caves, now do you see eggs? 1 Link to comment Share on other sites More sharing options...
Frosty.R Posted January 27, 2021 Author Share Posted January 27, 2021 @James Black I Just took a look and couldn't see any eggs at all around the cave My temp are constant 24 degrees in Celsius. Attached is what I'm currently feeding all my fish on a schedule Mon, Wed, Fri then Sunday then water change. Link to comment Share on other sites More sharing options...
Colu Posted January 27, 2021 Share Posted January 27, 2021 (edited) Sometimes my bristlenose chase other fish away from it cave it probably territorial aggression as they get older and get ready to breed Edited January 27, 2021 by Colu 1 Link to comment Share on other sites More sharing options...
gardenman Posted January 27, 2021 Share Posted January 27, 2021 It could be the number of plecos also. I have about thirty in my 50 gal tank and no fights, no aggression, they all just get along. I've got two in my thirty high and they can't stand the sight of each other. 1 Link to comment Share on other sites More sharing options...
Frosty.R Posted January 27, 2021 Author Share Posted January 27, 2021 @Colu Thanks for the info 👍 My Bristlenose didn't even care about the cave as my Bolivian Rams mainly had that spot - but now the Catfish won't let any of the fish in there so maybe they are getting ready to breed 😩........ I'll need another tank Link to comment Share on other sites More sharing options...
Frosty.R Posted January 27, 2021 Author Share Posted January 27, 2021 Thank you all so far for all the suggestions and advice 👌 Link to comment Share on other sites More sharing options...
Colu Posted January 27, 2021 Share Posted January 27, 2021 You could try puting more caves in the tank so each fish can claim a territory 1 Link to comment Share on other sites More sharing options...
