to MFK, Kenlim. I would like to say I am glad you joined the site if you are here to look for further queries. Unfortunately all your fish need larger tanks. If space and finances are not an issue, two oscars can go in a 180g. Since you have over five comets, please give them a 180g where they will readily grow well and be able to thrive. Good luck.I missed this...So what's the current tank size of your oscars and comets, Ken? Bear in mind that if you posted those photos for the sake of reaction, then this will be classified as trolling and further actions taken if found inappropriately trolling around.kenlim;3261210; said:Yea.. that is when they are babies.. Now i moved them to a bigger tank! shock?
Now I move them to a 90 gallon with 2 oscar only. The others I separated them. It's not a temporary tank.. I used powerheads for filtration. I have stones and coral substrate. I change 50% of water once a week, clearing poos.kzimmerman;3265048;3265048 said:There is also the possibility of some language barrier coming in here, he's from malaysia. We don't know if he had the oscars in there as a quarantine tank, a temporary holding tank for a water change/ tank maintenance, or what. To the OP, please don't take it hard, we see alot of people doing bad things to the animals we love somuch that we tend to get a little hot under the collar when we see it.
Please post some more specifics about you filtration method, do you use powerheads or airstones for circulation? Any substrate? Cleaning regimen and maintenance? It would help us understand the idea your going for here, and we would love to help you with it.

u may need more filtration if all u have is a power head moving water around.
