i got asked this question and i had no answer for it
are they alright for a new tank are the alright with a small tank and will they be qurrelsome with other fish and do they have any bad habits
as long as the tank is cycled and the stats are fine try and post the water stats if you can also the tank size if that is all okay then you will want between 4-6 of them and they are not known fin nippers i dnt think for 6 cherry barbs i would say a tank at least 15 gallons would be fine
its all down to individual fish you cant say that such a thing will kill another fish i mean look at my tank on paper should be a bloodbath but its all happy and peaceful obviously a bit of chases every now and then but apart from that everything is top
