    They are just like people, they will grow differently.  If they are both eating, they are fine.

hey, i have had two of these guys for a while (2 monthsish) and they live with a little blue gill, they are the same size and get along, but i noticed awhile ago that the two different species of fish looked very similar all though they are two different species that live on different contenents, also they seem to have the same body structure as other members of the cichlid family. could it maybe be possible that the blue gill is some kind of cold water cichlid?

    They will need to be over 14 months and around 10 inches. Are yours there yet?

Does anyone know any details on black blotches on an albino oscars face? When I look it up it says check the pH levels, and Ive seen the strips before but if it is messed up how do I fix it. I have a 3 year old oscar, got him in july so I am farely new at this but his tail has a bit of black and his fins and he has black splotches on his face and forehead area. And also does anyone know what levels I should be testing? Thank you. Ive been learning as I go.

    Your Oscar has head rot. Happens alot with Oscars. It's caused by too much activated carbon in the filter, poor diet, or lack of water changes.

    get a multi test kit and test all levels. there are drops that can be used to increase or decrease. How often are you doing water changes?

Hi, I am getting a 150 gallon tank that will have( and I meen will) 1 red bellie pacu, 3 senegal bichirs, 4 firemouth cichlids, and a pleco. I was wondering if I could put 3 or 4 oscars in there to keep the pacu away from the other fish. the pacu is owned by my science teacher and has unfortuenetaly gotten a like for meat but I would like to teach it to eat fruits and vegis so it will be less likely to hurt the other fish.P.S.,should I put the pacu in first or the other fish starting with the least agressive ones so they can establish teritory?

    You can do what you wish but doutfull more than one of these fish will survive. Tank is way too small. You have carnivores in there and if it will fit in their mouth it will be food.

    I could put in the pacu last so all of the less aqqressive fish can establish a territory and mabye even keep the pacu in check. Though I would rather recommend a green terror instead of a oscar (I own one they are very smart and in my opinion looks more smart than a oscar which also grows I think 3 inches longer). Though I think a green terror would keep the pac in check though that is my opinion and you should still check with the experts to see what fish would be the best.

    Before you can get an accurate answer I would need to know the size of each. There more then likely won't be room for the oscars. These fish all grow pretty large. With the group you have I would put pacu last.

Can I keep an oscar with some gold inca snails or will oscar find it as a fun chew toy?

    I believe your Oscar would think it was a great fun wonderful chew toy.

I was wondering if it is possible to breed oscars and what are the breeding requierments, like tanksize and telling if it is a boy or girl.

    Oscars are also called velvet cichlids and they do pair. Animal World article on monastic cichlids is a start with learning monogamous cichlids breeding Another article I found might be of help Breeding Oscars

    When you say they are not growing - how long have you had them? Oscars grow fairly rapidly but it is like watching water boil. When you watch them every day, they don't seem to be growing at all and then all of a sudden they are larger. Check the article from Animal World on feeding and tank enviornment just to make sure but probably just not growing as rapidly as you thought they would. Check though.

    get a bigger tank

    Oscar growth rate slows at a certiant size. And you will need a 125 gallon tank fo two oscars.

We have had an Oscar for 6-7 years (he's 10"long). The one thing we've learned is: NEVER FEED THEM STINK BUGS! Our Oscar was fine until we fed him those nasty bugs, now he's sick all the time. I repeat: DO NOT GIVE THEM STINK BUGS!

P.S. Exactly how aggressive are Oscars? I mean, how big does a tank mate of an Oscar have to be for it to not get bothered if the Oscar's 10"?

    If you scroll up through the above article, it basically says if there is more than the Oscar in a tank - eventually there will only be the Oscar. They are carnivores and predators and will eventually have the tank to themselves. I wouldn't recommend a tank mate for this fella. Even if you get a larger fish, there is going to be problems.
