Back when I was around 14 I had a large finally, 75 gal. Stocked said tank with many many fish, didn't know anything about keeping fish or cycling yet, in particular 6 clown loaches and a red tailed black shark, tetras etc etc.
So after a while my clown loaches started to drop one by one. I couldnt understand what was happening as they looked healthy and all other fish were doing okay.
Well it turns out that the biggest of my clowns and the shark had formed a bond. Both would sit under a log together and when another fish approached they would bash the living #$%# out of it. Seriously brutal stuff. Think, James bond strapped to the chair and that guy swinging the rope, that bad. This duo tallied up to at least 15 fish until I decided to separate them. Shark sadly died at age 5 and the clown continued till 10 which leads me into my second story.
Not done with his bullying I found it hard to locate this fish, he moved a couple times between varying sized tanks. Finally ended up in a 20gallon (too small a tank again), which he started wreaking havoc in.
Well one day I get home from work and I soon after hear a noise from downstairs. Went to check out the noise, baseball bat in hand and could not figure out what was happening. Flapping it sounded like.
Looked around, located the area and found a bunch of files with water on them. After looking into an envelope I saw mister clown loach lying there looking slightly pickled. Threw him back in the tank and all was good again.
Covered tank and thought that was it...wrong. 3 more times I got to him in time, the fourth attempt had old clowny finished. Leathered and stiff his final resting place had him sitting upright underneath the cabinet.
To make a short story long huh. Sorry everyone
