Red Tail shark thoughts.

I have all the fish in my sig. I have few fights, the red gourami chases the blue gourami when he crosses the half way mark of the tank for a half second but they never fight.

My red tail shark will chase the cherry barb if its close enough, but spends most of his day harassing the serpae tetra, who is almost as big as the red tail. The serpae was in the tank first, the serpae is going on 2 years old. Now that said when I moved to the new tank we had a CAE who harassed the red tail until we ditch the CAE in a friends tank. The serpae and the cherry barb look great and act happy, in fact they have gained color they never had in the old tank.

I read as many sites as I could find and they all agree the only fish a red tail should harass is another shark. Why does he hate my serpae, and to a less degree cherry barb. Has anyone else had problems with red tail sharks? Do I need to ditch the red tail to the lfs/friends?

Thats what I was afraid of. I know the two male gourami's don't care for each other much but I have never seen them chase each other further than there territory's which is less than 4 inches generally. The RTS will chase the serpae all the way down the tank and back up again.

Ya thats first on my list of to do's. He has tried to pick on the gourami's but they don't take any crap from him. He is afraid of the danios when they are in a group. He doesn't care about the snail or cory's. Its funny he stays in the same cave as the raphael cat, until I turn out the lights but the raphael is skittish of everything in the world and tank, and he is the biggest by a good inch.
