∙ 11y agoThe Oscar fish naturally stay calm when they are in a pair.keeping more than two Oscars in the same fish tank can cause then to get aggressiveso keep two Oscars at the max in one tank.
If the tank is large enough. For rearing young Oscars a 50 gallon tank is about right for 5 fish.
I would advise at least an 8 foot long by 2 foot square tank for that many Oscars.
I do
If your tank is at least 8 foot long by 2 foot high by 2 foot deep you may get away with a couple of each.
The Pacus are vegetarian and pretty harmless but they get very very large weighing in at around 30 Kgs (70lbs approx) when fully grown. Oscars are tiny by comparison. When fully grown they are only about 1.5 Kgs (4 lbs approx). Minimum sized tank for a couple of Oscas is about 72" x 18" x 18 ". You would need a very large tank maybe 10 x the size the Oscars need. Something that holds several thousand gallons of water to keep Pacus successfully.
hi im 13 ive had Oscars and are sensitive to nitrates you should be changing the water regulary and should have an air pump and they should have a big tank and not to many tank mates hi im 13 ive had Oscars and are sensitive to nitrates you should be changing the water regulary and should have an air pump and they should have a big tank and not to many tank mates
Tiger Oscars really should only be kept with Tiger Oscars. if you can find a fish that can grow to be equally large and have the temperament to survive with an Oscar then by all means try to keep them together, but Oscars will eat anything.
NONE Oscars are really messy and grow up to a foot! They need at least 50 gallons. For a 10 gallon I recommend some guppies and neon tetras.
You might be able to get away with it, but honestly i don't think it's a very good idea. The Oscars are likely to nip the fins of the koi. Oscars are much more aggressive
To keep your tank clean with three Oscars, perform regular water changes, vacuum the substrate to remove waste, and ensure proper filtration is in place. Monitor water parameters like ammonia, nitrite, and nitrate levels to maintain good water quality for your Oscars. Additionally, feed your fish appropriately to minimize excess waste production.
It all depends on how much other fish you have in the tank. Oscars need a lot of room so if there's tons of other fish in there it could cause problems. But if you have a couple it would be fine. If its a male Oscar its probably best you don't have them in a tank with any other Oscars. I volunteer at a pet store where they sell the fish so that's how I know this..
