doent sound like a problem, different fish different personalities, just like people. What size tank do you have them in?

Let's get the tank size and filtration so we can help you out more with this. Was the tank cycled? How large are they? Are there any other tankmates?

ok well i have them in a 10 gallon at the moment, there maybe an inch each, and my filtration is a aqua clear 20 . im probably in the second stage of my cycle.

i dont know how hardy oscars are but i dont think they are the best choice to cycle the tank with. I hope your gonna get a bigger tank cause oscars get big and you will probably need like a 75 for them when they get mature. also an ac 20 probably isnt enough for that tank. an ac 50 would be much better

Ooooookay now. Let's be clear that you will need at least a 75 gallon tank with a LOT of filtration for the 2 oscars. You need more filtration on your existing setup, and oscars are not particularly good fish with which to cycle. Even growing them out in a 10 gallon is not a good idea.

When you say you are on the "second stage" of your cycle, can you elaborate on that? Do you mean you are starting to see the nitrIte spike?

ye im starting to see the nitrite spike, and dont worry this tank is only a temporary tank im saving up to get a 75g canister setup, i just got to wait to get paid.
what do you think could be making them hide or lie on their side like that?

11-04-2007, 08:33 PM
what do you suggest for more filtration on the existing 10g?

The fish are highly stressed. Lying on the side likely indicates some poisoning, nitrIte or ammonia. Performing a cycle with oscars in a 10 gallon is torturing them, but...on to your next question.

Filtration for 2 oscars in a 10 gallon. I would recommend an AC50. Then again, I wouldn't put them there to begin with. I really hope you are able to upgrade to the larger tank within the next 2-3 weeks.

Filtration for the 75 with 2 oscars is going to have to be hefty. Large canister, maybe 2, plus a large HOB is where I would go with it.

What canister filter, and hob would you suggest, i was thinking of going with a Eheim ecco 2236(up to 80G) and as for HOB im not sure i need some suggestions

i also found a filter that sounds pretty good called Penn-Plax Cascade Canister Filter 1000 for up to 100 gallons. have you ever heard of this one? is it good?
