I have a tank with Discus, rams, khuli loaches, otos....
Anyway, I did something stupid, but the result is unexpected. A LFS was giving away fish, and my wife fell in love with a black and white molly. I got it, thinking that it could stay in my tank while I hunted for a free 10 gal tank.
Note I understand the water parameters are very different, and I did not change them...the tank remained a Discus tank.
Well, it turned out the molly is evil (like in the SouthPark episode). It immediately started to harass all the other fish. I mean, non-stop. I would tap on the tank when I saw him doing this, and he would swim up to the glass and look at me like "what do you want" By the time I got a tank, it had killed 2 of my Otos, 3 loaches and one Discus (twice as big. I am so pi$$ed with myself for getting it.
Anyway, I got a 10 gal, and put him in there and he seemed fine.
Then yesterday, I had a Ram that looked a bit sick, so I figured I would use the 10 gal for an observation tank (hoping in the back of my mind the molly would have calmed down over this time). Within 10 seconds, the molly was on that Ram, never letting up....like a mad man....
So anyway, I put the Ram back in the main tank (or it would have been dead by now) and I have a 10 gal with nothing but a molly in it.
Because I won't kill it, and now that I have told everyone he is evil, none of my friends want it, I am stuck with it...I am going to make a divider and divide the 10 gal into 2 5 gal, so I still have 5 gal to work with the sick Ram...
But still, I have had fish for many years, and I cannot remember ever having an evil Molly before....was I just lucky? Or do I have an evil fish?
Is there a method to his madness?
