I think when your oscar is full grown it is going to be hard to have more than one oscar in a 75 gallon. If it were me I would put 2 oscars in there even when they are a bit bigger. In my experience when I had my 75 I had a few fish in their. You could do jack dempseys too. They are usually great tank mates. I guess it depends if you are looking at upgrading to a bigger tank someday. The 75 could be a temporary grow out tank but if these fish are for keeps and this is their forever permanent home, then you will want to stay small on numbers of fish for sure.
75g oscar
- Thread starter Confidence
- Start date
definitely only one oscar, a 75g is the minimum tank size for a single oscar, 50% weekly changes is good, just make sure to keep an eye on nitrates when he is older and do a larger change if they get above 20ppm.as far as feeders, NEVER feed those feeder goldfish they are very unhealthy for him even if they aren't carry any parasites, if you really want to feed feeders then you can but do like minnows or guppies or something and make sure to quarantine them for a month before hand to make sure they are pooing normally (white/stringy poo is a sign of parasites) and dont have anything else abnormal going on with them. feeders are just too much of a pain for me so its not worth it, i just do pellets and the occasional insect, shrimp is good too but the staple diet should be pellets with the other stuff mixed in as treats. as far as other fish i think you could get a couple pictus cats for the bottom, they look cool and are active cats that you will actually see unlike a raphael cat that you will never see, and could even add some high bodied tetras as well if you really wanted too, you would just have to make sure you added them at the same time as a very small oscar and that they get big enough, and high enough to not be considered dinner once older (silver dollars will be too big for a 75g so dont get those) Good Luck Os are great fish!
I have a veil-finned albino for about a year now and his fins are sweet. I think they are just hard to find but I would recommend that if you come across one

I agree with everything but the pictus cats. They can get 6''-8'' full grown. Pictus cats are active open water swimmers, and are more preditory then bottom feeders. I have silver dollars in my 72g and agree that they are too big for a 4'' tank. One of the major problems is that they are very skittish and can kill themselves by hitting the side of the tank. I wouldn't add anything other then an oscar. After my O is gone I am going to only keep smaller cichlids in the 72g.
Also no corries-the O will out grow and can die from trying to eat one. Corries have a spine on the dorsal fin.
Jack Demps do NOT make good tank mates with Oscars BTW. I would get a little more filtration for this tank also. Another HOB or something similar.
your are definitly doing your research and i know your new oscar is going to be a happy camper..just feed good varied diet... do water changes on schedule..take out all uneaten food..{usually not a problem with an oscar lol} and give him lots of attention.. oscars can be such a fun fish.. they have enormous personality...active when they see you and so excited to eat they will eat right out of your fingers.. cannot wait to see him..

Depends on the fish, i have a jack with mine and they get a long fine.
Ok here is my experience, i have had my oscar almost 3 years, he lived his first year in a 40g with regular water change every week but as soon as i got the room he went into a 125g, I did regular water every week of about 40%, nitrates <5, fed mainly NLS pellets, and a couple times a month he got a night crawler and some homeade food.
Well he is now developing HITH with good water quality Nitrates <5, since i have harder water with a high PH, i added more driftwood, and started changing his diet more, i am feeding him NLS, Nightcrawlers, red worms, algae wafers, wax worms, and frozen homeade food.
So to sum it up, just keep your oscar a lone in a 75g with regular large water changes every week and vary his diet a lot. You will love your oscar as i do mine, they are an awesome fish and have a great personality. Ow and a warning, if for some reason you have to put him in a bucket, and you look in the bucket and he looks dead, he is not, they are excellent at playing dead.
Sure they make great tankmates, Oscars aren't really aggressive, Jack Dempseys aren't so bad either. Just get a tank that is big enough and don't put them together in a 4 feet tank.kevinfleming21;4375297; said:
feed your oscar quaity pellets (hikari cichlid bio-gold+). its expensive, but worth it. supplement his diet with sinking carnivore pellets, algae wafers, frozen blood worms and freeze dried krill. I use hikari, just read the label and make sure the blood worms and krill have vitamin additives. Resist the temptation to feed live fish or worms, your oscar will eventually get sick.
you could get away with one convict in addition to your oscar. tetras, barbs, corys; they'll all eventually get eaten.
