My male is horrible. GThe female is cool, she will chase off any other fish that mess with the baby tiger barb though. The male was chasing my female so i moved here into my other 10 gal till i could find a nicer and bigger tank. so i kept the male in the 29 gal. He chases everyone, though when i show up he wont do anything. the minute im outa site (still there but away from eye shot) he starts chasin them. I think he has learnt from the last time i had him in the divider. i have found to sort a fish out, put in the devider leave them there for 24 hours, let them back in and they wont do a thing again. i dont know how but it works. lol. Though i dont know what happend today to him but now he seems all nice to the other fish. Go figure. Oh and i tryed move my female gourami into a bigger tank though she was sad without the tiger barb so i moved her back, i couldnt move the tiger barb with her because of the tetras in there.
