Yaa that is fine in my opinion
You can expect your Oscar to get some where around 25 - 30cm so those tank dimensions seem fine for him
Just make sure there is enough open swimming space.. Especially when he reaches a good size so he can turn properly
Try do at least a weekly water change
but otherwise best of luck! Oscars have great personalities and make for great single wet pets
That size sounds like a standard 90 US gal tank. Will hold a single Oscar fine. Heavy filtration and lots of clean water will give you a very enjoyable package. Oscars grow fast and are a messy beast, the more clean water you provide, the better they will do.
Thank you both so much, i know this is an extra question , but do you think rocks like Lava rock would be a bad idea? I would glue them with silicone so they don't fall on the Oscar, but is there the risk of injury?
Lava rock is coarse/sharp edged and Oscars have a knack of getting nicks and cuts from everything. I would suggest a rounder, smoother rock. Oscars arent much for getting under things, they more like to hunker down behind some structure for rest time. Some rock and driftwood on bottom suits them better
I will post a thread on the lounge when it's all set up. I undrstand that a single oscar is pushing it , but are their any tankmates that would fill the bill concerning the oscar and tank size.
I heard that catfishes are very dangerous with oscars as their pectoral spines would tear up the oscars throat/internals if the oscar tried to eat the catfish... You think Pictus cats would be ok?
