does any one know the most aggressive aquarium fish?

Question

i want to try to find out why they are so aggressive

Answer 1

African cichlids, notably those from Victoria and Malawi. While many will consider oscars, piranhas, gars and etc. as being aggressive but their aggression is largely linked to eating; not just being plain nasty.
A 4-6in Lake Victorian cichlid will take on a 24-36in Nile perch as if it were a guppy. Many species of African cichlids have aggressive behaviors which know no bounds and will attack intruders that are many times their own size.
Of course the aggression found in Eastern African and Central American cichlids is due to the fact that these fish live in low-oxygenated waters and thus food is very scare. With the lack of prey in their environments these fish have become more and more territorial and fight for food and breeding sites amongst themselves. Those that cannot hold territory often die or fail to reproduce and hence the most aggressive fish can only succeed in passing their genes on.

There are distinctive solutions, staring on the size of your tank and the species and sizes of your danios. p.c.. one staggering on your issue. you could divide the tank, protecting the undesirable actor on one component of the divider. i like to divide a tank in 0.5 diagonally with somewhat "window" plastic that many shops sell to interchange a broken glass window. it would be decrease to the size of the interior diagonal of the aquarium and the top of the interior the aquarium from backside to the backside of the tank physique. you purely bend it to place it in place. upload a sponge or field clear out to the component away out of your clear out. you at present fairly have 2 separate aquariums yet once you seem by the front, it nonetheless all sounds like one without the detraction brought about via a super white divider demonstrate that the puppy save sells for better than you need to purchase the window plastic and the greater small clear out for. ensure the heater would not touch the plastic which melts below severe warmth. via putting the heater interior the back compartment, the warmth will mixture by the completed tank. regardless of each and every thing it extremely is not any longer watertight on the backside or ends, merely fish tight. you could retrain the meany. There are small plastic hinged balls for putting small products interior the dishwasher. style of like a hamster ball for a fish, the way we can use it. placed the fish interior it and return him to the tank. He can nonetheless eat and a few fish can push the ball around swimming everywhere they choose for, yet they might't assert themselves against the different fish. After some days of confinement, he will lose his spot interior the pecking order and be meeker whilst first released. some fish will learn after a time-out or 2 interior the ball, yet fish who run greater on instinct than suggestions ability might not at all learn. If the tank is vast, you have "overfiltered" the tank, and the size distinction between your fish isn't severe, including greater danios of a similar sort to create a school of a dozen or greater will save the aggressive danio busy staring at his very own tail fin rather of finding out on on his tank pals. i'm hoping certainly one of those recommendations will greater healthy your issue.
