oscar compatibility
 
alright so i just bought two juvenile tiger oscars i think , around 1.5 inches big. i have a 70 gallon and will probably move my two pairs of walking catfish in the 70 gallon. the catfish are around 14 cm. im wondering if i should buy another pair of oscars because according to the research im doing they should be setup in schools of 6 or more. but im not sure if i have enough room for that many considering the mess they make. also i wanted to put in another small school of fish if i didnt add another pair of oscars, but im not sure about the compatibility. i was thinking along the lines of dwarf gourami , or croaking gouramis. i dont want to add any rainbow sharks or red tail sharks or other cichlids i have a 30 gallon for each of those seperately. and i just dont like bala sharks, any suggestions on which fish i should keep?
any suggestion is appreciated.

I wouldn't add anything else. A 70G tank is a "good" size for one individual, and having two is already overstocked because of their waste and messy nature, plus of their size. You need to stock dependant on adult size, and not just how big they are right now (which will be 14"+).

alright but wont that surely lead to fights between the two?

Adding two more oscars will absolutely overstock your tank, plus it would likely lead to more aggression issues rather than alleviate them. The gouramis you mentioned would get the stuffings beaten out of them by the oscars.

alright how long does it for an oscar to grow big enough to start making a real mess in my tank size. mine are about an inch and a half right now. i was considering getting another pair that size just for a while so that when they grow i get lucky and theres a pair. Then i can return the other two.

I have two Oscars in a 80 gal. They are happy and not quite fully grown at 10" each. I got the albino 10 months ago and he was 2" long.The black one I got about 8 monthes ago, he was 3" then.They each grew about 1" per month. They have slowed their growth now that they are older. I would add a couple convicts. They are clean and very easy to care for. I have two in with my oscars, they get along great, actually they completley ignore each other.
Oscars REQUIRE very good filtration.
Here is a picture of how big yours will be in about 9-12months.
This one is somewere around 11-12 months old

Has anyone ever heard of a "grow out" tank? I disagree that the maximum tank size should be used right off the bat. It is OK to have a smaller tank while the fish(es) is(are) juvenile. Not a single one of you would immediately buy a 300g tank for a 4" arowanna. Na'ry a soul. I'd take odds on it. And I'll bet against all comers. I'm going to end up a very rich man.

You folks would drop a loaf if you were to see my 300g Mbuna tank!!! Talk about alot of fish!!! I'm spending too much on fish and boats to purchase good photo equipment.

One cannot say that the tank is overstocked without knowing the filtration system being used. I personally think that 10g-12g nanos are too small. (gonna catch some flack for that statement) If you're going to do it, do it right, start with a minimum 125g for your SW tank. The ocean is MUCH larger than any inland lake or river.

A 70g is plenty for the oscars until they reach a certain size.

Those pics are just beautiful. Those sights are the exact reason i went out and got a pair of oscars. They look just amazing , thanks for the pics bhone20. Btw what kind of filteration system are you using for that tank?

bhone20 06-23-2008 01:11 AM

I am using a Fluval 405 with ammonia chips, and bio-carb bags.25-40% water changes every week with a large gravel vac. My Oscars poop is as big around as a pencil sometimes.I also have a 9" pleco in there.If you add other fish, make sure you have MANY and different sized hiding spots.I bought my Oscars a turtle stand and sunk it in the corner, they used that until they out grew it.

BTW got any pics of them? I would like to see.

Herefishy makes a good point . not many people take into consideration the adult size that fish will ultimately reach. Otherwise there would be no need for the warnings on overstocking. Sadly , many people also have no plans on upgrading to larger tanks or increasing filtration to best suit the particular load . Instead they keep adding fish until there is not enough oxygen, filtration or space for the load and fish become stressed and ultimately begin to perish due to diseases brought on by poor water quality.Everyone in my view, should always consider long range plans for large fish and large numbers of fish in tanks too small. :(
