i jus recently bought a jag and i have a koi fish a goldfish algae eaters and a convict and yabbies will they live well together.? btw im a new fish keeper.
Depends on the size of the koi maybe the jag won't attack if it is a decent sized koi.
But it really is just a bad combination anyways, it is better to try some other cichlids.
Koi and goldfish are asian and jag is american, the habitat is different so the water parameters. Jag is a CA and needs a water temperatuure around 28 degrees with a PH around 7.0 whereas others more colder and higher ph. Even the size, Jag will try to kill them no matter how big the goldfish and koi are.
if the Koi are bigger it will be fine but you will need a very big tank koi get over 2' if i were you id make a pond for koi and get more Cichlids to go with the jag like Festae,Salvini,Green Terror,Herichthys Carpintis Escondido
