UK Aquarium Hobbyist Posted August 2, 2021 Share Posted August 2, 2021 Guys has anyone experienced this? I added a female convict about 2inch to my tank which holds 2x firemouth and 1x Salvini all living peacefully with 5x large corydoras. The convict has attacked all the Cory's targeting the barbs and eyes!! I've never seen this in all my years in the hobby. Have I just acquired a demon fish, I know this can happen on a rare occasion.

Guppysnail Posted August 2, 2021 Share Posted August 2, 2021 I do not own convicts but watched a video about them that said they are very aggressive and territorial. Link to comment Share on other sites More sharing options...
Colu Posted August 2, 2021 Share Posted August 2, 2021 You could put a tank divider in and separate him from the other fish or move the Cory's to another tank Link to comment Share on other sites More sharing options...
UK Aquarium Hobbyist Posted August 2, 2021 Author Share Posted August 2, 2021 Cory's are already moved. They would not have made it through the night 1 Link to comment Share on other sites More sharing options...
Biotope Biologist Posted August 2, 2021 Share Posted August 2, 2021 Convict cichlids are extremely territorial and aggressive as @Guppysnail stated. I think the reverse is true for me when I had a convict. Originally brought home a hand full of baby convicts to my sunfish. Only one survived, a male no less, and he was a puppy dog. Best friends with my gold fish and always thought he was a gold gourami. Never attacked anyone, if anything he was chased off the food by the gouramis. I had a tank of rejects, thus the eclectic nature of that story. I digress, for the most part I would not recommend convicts to any community tank unless you have other larger cichlids that will keep them in check. I have heard stories of them bullying timid oscar fish out of their tanks too. Link to comment Share on other sites More sharing options...
Patrick_G Posted August 2, 2021 Share Posted August 2, 2021 I had a convict when I was a teen. He lived peacefully with a Jack Dempsey and a Jewel. I’m surprised they all got along, but at the time I didn’t know any better and the shop was happy to sell me whatever fish I wanted. Link to comment Share on other sites More sharing options...
Steph’s Fish and Plants Posted August 2, 2021 Share Posted August 2, 2021 Females can be absolute terrors, especially if they’re breeding. I pretty much never recommend keeping convicts, and never plan on keeping them myself. one of my friends had a pair in a tank with a flowerhorn and some jewels and he had to get rid of them because they were beating the crud out of the flowerhorn and had shredded all its fins. The flowerhorn for reference was about 5x the size of the convicts. Link to comment Share on other sites More sharing options...
