meanest fish I ever knew...

What type of Piranha did you have?
All from the pygocentrus family are pretty skittish.
Get an elong, and you'll never say it's shy.
Alot of them attack the glass when you walk by.
The most aggressive fish I've personally seen was a snakehead.
Can't remember which type since it wasn't mine, but it was crazy.

As bad as they are in the movie "Terror at Snakehead Lake" (or something like that) that they show on Sci-fi?

Ah, Philip the Piranha: 'Never mind me, I'll just have a piece of everybody else's...'

I haven't any idea which one he was. I got him when a decoration fell over at my lfs. I pointed him out, having been pinned underneath it, no knowing how long, and they were just going to scoop him out and discard him. I offered them 50 cents for him, which covered a bag to put him in, took him home, and put him in my guppy tank. He was the size of a quarter then.
He grew to the size of my hand, was thick as a deck of cards, had a beautiful red-stained front on him, and that jewel-scaled blush on his sides, going to silver, a bulldog toothy look, and thrived on ground beef. He outgrew the guppy tank when he passed fifty-cent piece size. He used to lock onto one guppy and pursue him to the exclusion of all 300 others in the tank, weaving in and out, as said guppy became lunch. But I valued my guppies, so as soon as he could switch to ground beef, that was what he got.
 
Yep,
In FW it must be the snake head.(Channa micropeltes)
Had a big specimen when I was a kid, kept him with 2 huge Oscars they spilt the tank in between them more or less, one day I come back home and see one oscar top of the tank, on the water level and on his side, I see his friend cut into HALF , I dont have a clue how he fitted the Oscar in it's mouth but apparantly these monsters have another set of inner teeth that split the Oscar in 2, The Snakehead was laying on the gravel fat and happy with half an Oscar in his stomach.

I could never see it happened as the Oscars were chasing the Snakeheads from their territory earlier, I was also quite new to the hobby this was like 22-23 yrs ago....
 
red lip blenny for me
hes killing everybody in my tank slowly
im working on getting him out...no easy task
cute as heck but a meany
 
Ophioblennius atlanticus is the latin name for the red lip. I had a lawnmower blenny that was a killer, both in my tank and in a friends tank as well.
 
My, oh, my---I never thought of a lawnmower as a potential problem: they've always been model citizens in my tanks. I'll revise my recommendations!
 
The LM blenny I received came from a friend who had several passive fish in her 90 gallon (seahorses, jawfish, firefish) that this fish would either chase or attack outright (seahorses). I had a pretty rough and tumble 180 reef (angels, tangs, clowns, rabbitfish, pseudos) and I never anticipated any problems taking this fish in, and there wasnt any trouble for several years until the blenny suddenly started going after all of my deep bodied fish, rasping their sides with his mouth. He really went after my asfur angel and the angel eventually died from a very nasty infection but this blenny would go after every tang and foxface as well. Nasty little fish, had to tear down the tank to get him out. I have seen many LM blennies that are just model citizens but I know I'll never keep another one. :(
 
Fish can learn, at a pinch---I'm convinced of it; and that one clearly learned a very bad food source.
 
Yeah they do -

My meanest fish in my tank right now is an anthias :eek1: he pretty much killed a blackcap basslet, ate 2 yellow clown gobies & now likes to lurk in the blackcap's old cave. He must still be gloating- lol -- I never heard of anthias being cave lurkers.

I had a bicolor blenny who murdered a royal gramma once :confused:

Not a fish --- but I had a small Carribean mantis that clearly used to love making an idiot out of a huma huma trigger - that was hilarious - I wish i had a video of the mantis peaking around the corner at the trigger while the trigger was going,"Where'd he go! where'd he go?" It was like Tom & Jerry :lol:
 
The meanest fish I ever had was a false percula. I don't know how many times that thing jumped out of the tank trying to attack a hand, any hand, that happened to be doing anything in the tank. It would land 4 feet down on cement (should have left it there) only to bite the hand that saved it's life when in the tank again. It finally lost the battle against a powerhead that the guard fell off of. Nobody was too upset.

Some fish just don't make any friends in the tank, do they?
 
My Clown trigger is the meanest fish I ever had , he even try to get me through the aquarium glass when i walk by.
 
Tha'nks, Spaceman. I never knew. He was with me through college and after. Pretty fellow.
 
C'mon guys,

The big undulatus will chew 99% of the fish mentioned in this thread!
And Piranha? what Piranha? That snakehead I mentioed wouldnt even bother to munch Piranhas cause they're too small for breakfast.:D
 
What I've heard of the undulatus on this thread, I think you may be right. A real customer!

Well in that case I guess someone should mention tiger sharks or whatever & be done with it -- I thought we were talking personality:D
