Tamable using fish baskets from aberration. They attack the baskets once placed. It is a good strategy to pen then in with fence foundations and walls, or kite them to a pen. Place your basket on the other side of the wall and catch.
A piranha is tameable in Abberation using the fish trap. It has to swim into it. Once you release it from the fish trap, it will be tamed. Great tame in packs, they can kill a good amount of low to mid level groups of players.
Can be tamed in abberation however you have to force feed it in it's inventory it will not feed itself.not worth taming. To tame. Jump in the water and get them to beach themselves. Kill the ones you don't want. Place fish basket wait near fish. Wait till it initializes. If the fish leaves range kite it back and start over. Then pick up trap you have five min to get them to what ever body of water you want them in. Remember you must force feed them like a baby after hatching/birth. For the entirety of their life.
Get them on the shallow bit of the water and place a fish trap but you have to sit their feeding it however a pack of these are useful but one will die so keep them safe also watch out they do pack a punch
