I have had my 3 kuhli and BN together in the same tank since April. (along with a few guppies)
Over the last couple of months the BNs bristles have become more prominent and he sometimes has his ododontals out.
But now, every evening when one particular Kuhli comes out lookign for food, he immediately goes over to it and tries to swim with it, quite funny when the kuhli is doing his/her figure 8's and the darn BN is trying to go with it. The Kuhli gets a bit fed up and goes back into hiding.
I wondered if the BN was just being friendly but now he tries to hog the food as well.. is he being territorial , should I shift him to another tank or look at rehoming him ? The Kuhlis are becoming more shy.
I don't have room or the inclination to try and put a female with the BN. is he lonely?
