New fish
So i have an oscar and a plecko looking to get a new fish tonight. I have a 29g tank. I was interested in getting some mollies or even possibly a school of fish but seeing as the oscar is an aggressive fish im not sure what he is compatible with. If anyone could give me some ideas or help on what to expand my tank with.

Hey hopefully you do have a bigger home for the oscar right? they can get pretty big i think like 12" in that range and a 29g will be to small. As far as whats comp. with them im not to sure but im sure someone else will give you all that info :-D

Tank is way too small for an Oscar and therefore too small to add anything else with it.

Sorry but Oscars need bigger tanks. Clicking on the highlighted Oscar in the posts will lead you to the profile in our profile section, there it lists the minimum tank size for them, which in this case is 75g. Unless you can provide a bigger tank for the Oscar, then it will have to be removed otherwise it will simply be very unhappy in that tank, open to disease from a weakened immune system and wont have a very long life span. They grow fast so this must be taken into account.

I didnt know that he oscars would get that big. This is my first tank so sorry if i sound like a dumbass. Ill keep in mind to get a bigger tank for oscar but im possibly thinkig an angel fish or molly. Ill most likely play around wih t to see what goes and what doesnt. How quickly do the oscars grow? and are they really as aggressive as ive heard? Because he doesnt seem to bother any fish.

Please do not add any other fish to the tank.

You will simply be wasting money, the bioload that the Oscar and Pleco are going to create is enormous and unlikely your biological filter will be able to handle it in such a small tank.

Oscars can grow 6" in a matter of months and sometimes sooner if they are well fed. They eat an awful lot and if not fed enough will see anything small enough to fit in their mouths as a quick snack. Yes they can be aggressive and hence why they need a big tank.

Agree with Tazman, that oscar will not be happy very soon in that size tank. My oscar is very aggressive and will attack anything you put in there regardless of size, but my friend's is much calmer and is happy with a school of silver dollars swimming about. With a bigger tank you might be able to add more fish but it all depends on the personality of your oscar.

I just recently purchased a convict cichilid. It is starting to get some orange on its body and it fins. Just wondering if there is anything to worry about or not?

Female Convicts will have orange in their belly area.

Are the convict and the oscar in the same tank?

PLEASE for the sake of your fish DO NOT add anything.

The tank is unsuitable to house all those fish to adulthood and all your are doing is wasting money buying more fish.

Oscars and convicts in a 29g tank is a disaster waiting to happen. The oscar is simply going to grow too big for that tank. At Minimum they need a 55g tank but a 75g or larger is more suitable.

The bioload created from all these fish is going to create water quality issues which in turns leads to stressed and possibly diseased fish. Oscars eat a lot of food and grow quickly.
