Tripletail;1043531; said:well, suffice it to say that I didn`t think they would show aggression within two days being together. I HAD them both in a 35 gal.tank full of minnows.That didn`t stop aggression,woke yesterday morning and one of thier tails are gone[mauled half way up the body] I seperated him but his injuries were too much,this morning he died . now there is one. I was going to try to keep them with my 10inch redtail payara ,thats not going to happen,he will stay apart from other payara. Just a heads up of my mistake.
the small tank was deffinatly the problem, ive had this happen numerous times. they just feel too close to the other and have to claim their territory. they would have lasted longer in a bigger tank for awhile, until they got bigger then the bigger tank would be the same as ur 35 gal cuz of how big the fish have grown. my armatus is starting to pick on everyone except the rays.
