hi i think im going to get a shoal of 6 black widow tetra into my community tank, does any know of any aggression from the fish and what part of the tank they would mainly be?
They tend to stay around the middle of the tank. They can be fin nippers, so I wouldn't get them if you have anything with long trailing fins, like guppies or Siamese fighters, although in a group of 6 or more they might be alright; depends on the individual fish and whether you want to risk it or not.
125 litre tank 80 cm long.
contains albino corys bronze corys kuhli loach and glass catfish i expect them to be ok with these other species, would i be right in saying that?
