yes but i am not buying them at this size. therefore it will give me time to prepare a new tank for them when it is ready. i just see no point in getting a 125 gallon tank for 2 two inch oscars at the moment.

Hey, i got mine small too, best idea to get them eating out your hand and friendly, feed them varied foods, flake, bloodworm, normal worms, prawns, the lot, mine are currently 6-8inch, about a year old =] so quite a while!
Good luck!

But they grow very fast and the larger tank will better allow compatibly. The truth is I don't know when you will upgrade. It might be 2 months it might be a year from now. Please do not think I am attacking you directly I have seen a lot of abused oscars so I just want to make sure that they get taken care of. I don't know you or your situation so when I saw 2 oscars in a 55 a red flag went up in my head. Nothing personal. For a fish that can get 14-16", 55 won't cut it. And by the way when you use the term "pair" usually that refers to a breeding pair otherwise they are just 2 fish in a tank. Just keep an eye on them as they grow so they don't kill each other. Oscars are fantastic fish wen givin everything they need and I am sure you will love yours.

GL with your fish

I've no direct experience with oscars, but I'd like to make a more general comment on this issue of tank size and growing fish, since it is relevant to any and all fish.

Fish grow continuously, and they need adequate space to do so. It is perfectly possible to keep moving fish from tank to larger tank to larger tank as they grow. But, the critical issue is doing it soon enough. Without sufficient space the fish will not develop properly, and once this problem sets in, the fish is doomed. I'm not a biologist or ichthyologist so I can't say at what point this or that fish needs this or that much more space. The safest approach is putting it in more space initially, and keeping it in more space than what it might "appear" physically to require.

With the space (volume) comes the more important issue of water quality. This is where the small tank falls down. Not only does a fish, any fish, need sufficient physical space to "be itself," it needs that space for stable water parameters and conditions. Stuff like pheromones released by fish that you can't even see are in the water. In nature, all fish are able to be in different "fresh" water every second of their lives. We cannot hope to duplicate this in the largest aquarium. But we approach it with large tanks for the species and regular water changes. The smaller the space for the fish, the more often water changes are required.

So the point here is, make sure there will be suitable tank space for the fish when it becomes necessary, and this means a tank larger than what you think is needed at every step along the way.

My own personal practice is to never buy a fish that at maturity will not be well provided for in a tank that I now have set up.

Byron.

i agree with the other comments here, the problem is also when people think about ''bigger tanks'' they go by the length, e.g thinking a 6, 7, 8 foot tank is going to be more than big enough, but they also forget about the depth of the tanks, usually i come across people with very long tanks, but they are 1, maybe 2 foot wide and deep, which with small oscars wouldn't pose too many problems, but after a few months, can stunt their growth due to lack of space for turning etc, just be careful of that too and you should be fine :)

Byron brings up a very good point(as always). A larger tank allows waste to be diluted easier which means the water is easier to keep clean which is very important when keeping oscars. If you had a slower growing species like a green terror or a jack dempsey i wouldn't be too concerned about upgrading but since they grow so fast and get so big, I am worried that they won't get their room quick enough.
