Being Eatin Alive!

I have a chubby shubunkin like fish that i took out about 4-5 weeks ago to let it heal from the last attack from the ther goldies and I just now put him back in the tank and hes getting bittin up!? What is making my fish do this to him?

 

[WILDER]

Size of tank in gallons or litres.
How many fish and which type.
And water stats in ammonia,nitrite,nitrate,and ph.

 

[Tokis-Phoenix]

As wilder stated, you should give us more info on your situation so we can advise you better on what to do .

 

[Kiwigirl]

Isolate your fish again and come back with those stats.

Ok I took him out and hes got 2 more chunks taken out of his fins. We have one Koi and 3 goldies in a 10gal there all under 2inches long. Im getting a 20gal for christmas.

I think the main problem could be overcrowding. A 10 gal tank is only really big enough for 1 coldwater fish, let alone 4.

The 20 gal will help spread out the aggression.

I know though that once a fish holds a grudge for another, it can get pretty vicious. I have a dwarf gourami that hounds my platy. But without separating one or the other, there's nothing really i can do.

 

[WILDER]

Can see the problem aggression through to many fish in the tank and probably bad water quality.
Koi need ponds not tanks.
First goldfish alone needs a 20gal tank, then 10gal for every other one added.
Need excellent filters as they are massive waste producers.
I would take a sample of your water to the lfs and tell them to write the readings down for you.
And rehome some of the fish, especially the koi.

 

[samyboy]

if you have some space in the garden a small water feature will provide a better home for most of the fish then just keep a couple in the indoor tank

goldies need 10g minamum each. so u would need a 30g min. for those fish. ps koi grow to almost 2 ft or biger when fully grown

Ok yeah The water is fine and we are probubly going to get rid of the koi because its getting big + would hiding spots in the 20gal help the aggression issues?

 

[WILDER]

Even twenty gallon is not big enough even getting rid of the koi.
And to be honest i doubt very much the water quality is fine.
And no hiding spaces won't cut the aggression out.
Research the fish and do your home work before adding large fish to a very small tank.
Been there with my sister and had to pick the peices up and take her fish on.
