Pacu On Its Own?

    hi , got a tiny little pacu in with my silver dollars .. Growing him up untill he's big enough to go into the pond. I'm giving the silver dollars to my mate soon and my only worry is that my pacu has been schooling up with them ... If I take them out will he spend his whole time hiding ? Or will he get over it. Never had pacu before.

    Do you have a pic of it?

    Not sure how yours would do being used to the current situation of schooling, but my pacu became too aggressive when he reached around 5". He was in his own tank for years, and swam the entire tank, and never really hid. But as always, all fish are different in their own way...

    Pacus are schooling fish and should be kept in groups of 6+. When not kept in a big enough group they will be stressed and may become nippy or shy and are more likely to get ill and live shorter lives. He is probably schooling with the silver dollars for some sort of security because he doesn't have his own school but he will still be stressed because there are no other pacus.

    Agreed with @BottomDweller.
    Pacus, like their cousins the Red Bellied Piranha and Silver Dollars are schooling fish and like every other schooling fish require to be in groups of 6+.

    Personally, I've only seen a school of pacus in a 2000 gallon tank in a hotel in Malang, Indonesia. They thrive very well in there, and the best part are that they are the white variety.

    Are you planning to get a bigger aquarium? Pacus need a minimum of 400 gallons in an aquarium, and as bottom dweller said, they will get stressed if there are no other Pacus around.

    Bigger aquariam ? The pond it's going into when it's big enough it's about 40-50 meters long and 4-5 meters deep But thanks for your replies. Looking at getting a few more for the pond so il raise them up with this fella

    Took the SD's out today , he seems fine ... But every other fish is loving it .. The young indo Datnoid I'm growing out in the tank has never been so active now the SD's are gone... Would of thought it would have had the opposite affect having no dither fish now. Beats me ..

    Indonesian Tiger Fish can grow quite big, trust me I'm from Indonesia.On the top of my head I think they can grow up to 17 inches.

    What tank size are you going to house him in, a 60 gallon would be the minimum for a single specimen or are you going to put him in the pond as well?

    He will probably be in the 300 with the silver , or just be the sole inhabitant of the 125.. Not 100% sure yet . Yeah they have quickly become my favourite fish.
