Hi all,
my name is nick 30 years old father of one from london england .i recently purchased to beautiful 3 inch tiger oscars .and have them in a 4ft tank which i think is 37 gallons and 168 litres not sure if this is correct or not. anyway im wanting to know how many oscars can be held in a tank this size i also have x2 albino plecs in there about 5inch long , can anyone please advise as im new to oscars but not to fish. regards

Firstly welcome to the community.

Now regarding your fish and tank. Unfortunately it is far too small even for one Oscar. The plec will require nearly 100 gallons just for itself. So you have a bit of a dilemma. If you upgrade your tank to something much larger, I'm afraid you're going to have to do think about what you're going to do with the fish. The Oscar will grow very quickly and it won't be very long before you're having water quality problems.

Sorry if that's not what you want to hear, we have to be honest with you on here

hi thanks for that looks like ill upgrade to a bigger tank.thankyou for advice

thankyou all for making me feel so welcome much appriciated

welcome to the site.
please post data of your tank: length x width x depth
if it is 48" x 18" x 18" = 65 US gallon size. approx.
if that is so, you have few months to use it until upgrade
is available. of course, with good filtration, regulated
feedings to stunt the growth, and plenty of water change.
but that is not happy fish keeping. as OFL had said, bigger
tank is a must to avoid potential fish keeping problems.
