Hi I'm after some advice about my 2 new 5cm long l397s. There in a 4 foot community tank with some Cardinal tetras, rummy nose tetras. 2 blue Rams and a large pair of common bristle nose who have been breeding with the male still in his breeding cave. The tanks is a planted tank with plenty of wood, plants and caves. I removed about 10 other common bristle nose at around 8 cm a couple of days after putting the l397s in the tank, thinking this would be better for the new fish. Yesterday I noticed that one of the new l397s had been fighting and has suffered sucking damage on its back and dorsal fin. I have seen this type of damage on the common bristle nose that fight and they always recover. I also removed a male bn that I had missed that was harassing the breeding pair and I figured this was the culprit. Also today the damage looks slightly worse so my question is. Do you think that I should remove all the common bn as it could be the large female fighting (11cm) or in general it's better to not have bn and L397 in the same tank or could it be the two l397s fighting for territory now that they have the majority of the tank to themselves? Any Advice would be greatly appreciated. I would hate to lose a fish to some dumb error on my part. Thanks Chris.
