My Rtbs Aggressive Again!

[silky]

hey everyone, i have a red tail black shark about 3 inches long, i have noticed that he is getting more aggresive as the days go by. my tank is in my bedroom and when i turn the lights off at noght he chases all of my other fish(found in my signature) around like a madman. he doesnt really do this in the day. so last night he was chasing around all the fish as usual, when i woke however my albino algae eater was dead it has what looked like marks from fighting eg big bruises along its body. i was wondering if there is anything i can do to calm him down without removing him as he was my first fish
thanks

You could get a larger tank to give more territory. Not sure of it would work though. To be honest, most people who have a problem fish usually take it back and swap it for another.

.. the less you have... the more aggresive it gets...

i once had 1 tiger barb in a 20 gallon tank. cause i had no idea wat other fish i would get, a few months later when stick my hand in to clean out some stuff it always pecks at my hand and tries to attack it.

moral is that u should get more of that fish. now i have 10 of them in a 80 gallon
