Silver Pacu: Help Needed

[doomsays]

i had a small aquarium which i purchased 3 yrs back, but never had time and knowledge to take care my fishes. recently i purchased a sightly larger aquarium with following speci:

size: 3 x 1.25 x 1.25 feet
temperature : 25-26 deg C
filtration: 2 gravel filters , 1 sponge filter
ph: 6.5 -7.0

i had 3 gold fishes and 3 sharks (sizes: not more than 3 inch ) in my older tank. which as i told, never taken care off. and because of which, they dint grow to size, which they are expected to do after 2 yrs. anyway, i transfered them to this new tank.

soon after i purchased this tank, i added 3 pairs of tiger barb (size : 0.5 inch ) , 1 pair tinfoil barb ( 3 inch ). there wasn't much of problem.

but recently, i added 3 red bellied silver pacu ( size 4 inch ) . i suppose, this was a plant eating and peace keeping fish.. but it turned out to be a mess. after a weak of adding them, they ate half of my vegetation , ate my siamese shark and are virtual terrorist in my tank. they ate all the fins of my gold fishes and remaining sharks too. i feed my fish twice a day with grains and dried worms. and for past few days, i found water to be cloudy. i changed 50 % water but found same situation in the morning.

my question is: should i increase quantity of fish food so that they dont attack other fishes?? or should i put them in my old tank , and if so which fishes should be grouped together in my old tank??and how to get rid of cloudiness in my tank

size of my old tank : 1.75 x .5 x .5 feet

Your stocking is responsible;
Ok 39.8 gallons(us) tank;
With a Pacu; general accepeted tanksize (GAT for this post) 75 gal when young 250-300 gal eventually.
Tinfoil barb GAT 50 galls (at least!) should be in a group of 6 or more....
Your tiger barbs are fine.
Pacus are well known for eating small fish, they are also well known for uprooting your carefully arranged plantation.
You should always research fish before buying them,and research them well.
The cloudiness is possibly a combined result of the extra food you are feeding, the pacus rooting and a large excess of waste.
You need to return the tinfoils and pacu and start from the beginning...
Theres no point considering rearranging your tanks unless you are willing to buy a brand new HUGE one for the pacu and tinfoils.
Also why oh why have you got goldfish in a tropical set up?
These need returning as well. You could set up your old tank as a coldwater but your old tank would need to be 30gal absolute minimum, which from the sounds of things it isn't.
I'm not sure where you have got your supposed info from but it is way off the mark.
Research.....

Irresponsible is an understatement. For the love of the fish take them back while you still can and do a lot more research next time. Your pacu get three feet big. And Tinfoil barbs do need tons of room as germ said, IMO more than 50 gallons. If you dont have the time (or the knowledge) for this hobby then dont participate in it.
