Damage on ray's tail

  • We are currently upgrading MFK. thanks! -neo
Looks to have been chewed on. It will not grow back but will heal. I would suspect another ray is chewing on it. It happens, part of ray keeping.
 
Ok, but the motoro is 20+ cm over the disk and the pearl only 12 cm. Is it bad to keep rays of different sizes together?
 
I just saw the little guy biting the motoro's tail. So he's obviously a bully. Will this be a problem?
 
just keep an eye on it for now. my larger female has started doing it to my male this is the second time she has done it in about a month first time she did it to him it seemed to heal fine and the coulor came back could not tell till she did it again. just wondering how big is the tank? im wondering if the rays feel crowded my rays are ready for a new tank so in the next month or so there getting a larger tank mine are female moroto 13 inch disc and male marble 11 inch they are in a 6x2. are yours M and F ? which is biting which ? whens it happenning ? both times it has happend it has been at night time. my rays have been together about 6 month now and she has only just started to do this how long have your rays been together? sorry for all the questions but by sharing your observations we might find a common which could be the trigger and then it could be stopped.
 
It's 200x60 cm but temporary they only have access to about half the tank. I could split them and let them be on different halfs, I just thought they would like to be with each other. They are M (pearl) and F (motoro). The pearl is biting the motoro and it's seems to happen at random times. I mostly watch them at day time. They have only been together since sunday, so not even a full week.
