A 24" aro in a 125g tank is far from that oscar in a 10g. I would be more concerned with the lack of proper feeding and the excess of decor in the tank. Plus I'm sure this tank has not seen it's fair share of water changes.addicted2cichlids;1679948; said:thats sad for that aro. reminds me of a recent post on craigslist here in san diego. a oscar in a 10 gallon for sale! its a shame!
