Hey I have a 300 gallon tank
4 Severums 5"
6 Silver dollars range from 3.5" to 4.5"
2 Geo Abalios 4.5"
1 four line pim 6"
1 Bolt cat 12"
1 Clown Knife 10-12"
1 Bushy nose 5"

Lately Ive been waking up and noticing my silver dollars have missing eyes and one died. I know its the clown knife fish as i saw im take a strike at one the other night. Also my Severums have been getting beat up really bad.

I know that clowns will eat anything they can fit in there mouth but ive never had one with such a mean streak and attack fish they cant eat. The clowns diet is pellets and shrimp I feed him 4-5x a week.
Im at a cross roads if i do nothing i have no doubt im going to continue losing fish and/or eyes.

Any advice or ideas or do i need to decided if i want the clown or the severums and Silver dollars??

Thanks
 
Is this the one that was sitting at Coralville bay for a while in a 40b with a name?
 
Let me ask this. How much should i be feeding the clown. I feed a light feeding 4-5x a week. should i be feeding more often or more at a time?
 
You can feed him as much as you want but I don't think it'll help too much with what's going on.
I'm pretty sure they're nocturnal hunters. And with him being the biggest fish in the tank, you've provided him with plenty of late night snacks.

Yea the clown knife gotta go imo . At my lfs they had one about 8 inches in with an orino peacock bass ( that I was gonna buy ) that was about 10 inches and the clown knife completely destroyed him one night after they closed up.
 
I have a clown about of 22-24", was a terror when I got it at around 5" in the grow out tank, once I moved it to the 500g never had a problem, go figure?
Does it have a cave where it can get away from light during the day? they become stressed otherwise.
The info given above is probably correct, you may have to rehome it, they are ferocious nocturnal hunters.
 
Thanks everyone for the advice. I think my best option is to re home it, as sad as that is....
I will be taking it to coralville bay in iowa city iowa if anyone is in the area and wants it.
I know they are nocturnal hunters and i ive had several in the past and never had one readily attack other fish they are incapable of eating ( and yes i know how big of a mouth they have!)
Weird thing is all these fish have been together for months and out of know where it started attacking other fish. To bad i guess this is what you get when you try to keep large aggressive fish... thanks again for the advice
