The aggressive is typically true. There are exceptions, but few and far between. Most often the worst of the aggression is reserved for their own species. If yours aren't consider yourself lucky.Witalis007 said:The description for M. lombardoi is that they are EXTREMELY aggressive and that they do not recognize their owners. This is simply not the case here. I have a few other fish and they live together just fine. When I approach the tank they swim toward me. There are a few other discrepancies that I came across. This is exactly why I was having a problem positively identifying these fish.
