Oscars are really awesome fish with loads of personality, playful and messy....Not just poop machines but eating habits too.....It almost looked like all the food is being expelled through their gills than what is going in their stomach....lol.....
This is my albino...
I had 2 in my 75gal and in about 12months they had outgrown it and I had to re-home them to a friend that had a 225gal after they spawned for long term keeping....I miss them too...such cool fish and I swear....if they could have gotten out they would have followed me around the house....lol......They never liked the way I scaped the tank and would rearrange it and would even take the plastic plants and toss them out of the tank after they got done playing with it. They would carry it around, play tug-o-war with it. They killed a couple of heaters, destroyed the intake on one of the filters.
Water changes-they loved water changes....lol.....I would siphon all the water out with one python that I would have on gravity to drain outside and another python I had hooked up to the sink to refill. First I would vacuum really good removing about 75% of the water-Then I would start refilling the tank and when it was almost full-I would start draining the tank again until nearly empty and the Oscars laying on their side-Then I would start the refill and they would play in the fresh water as it flowed in...so fun to watch....I did this on a weekly basis in the 75gal with 2 Emperor 400 running (
turned off for water changes)
I fed them-fish that I culled, marble crayfish, my homemade food, fresh crappie filets and cichlid sticks....I wouldn't recommend feeding feeder fish-due to poor nutrition and parasites-unless you raise them yourself and gut load them.
HITH-as long as you provide proper nutrition and maintain good water quality-it shouldn't be an issue
I miss my Oscars....but I didn't have a big enough tank to keep them and I wanted to plant the that tank...lol.....So I got one spawn from them and re-homed.....
