The first time you lay eyes on a juvenile Tiger Oscar you’ll find something different. You’re no longer simply housing a pet; you’ve adopted a demanding creature. The combination of an orange/red body with bold black stripes are eye-catching enough, but it’s the personality that reels you in.
These is smart fish. They are curious fish. They will frequently know who you are and they begs for food from the glass.
It’s easy to fall in love with these fish quicky. The love comes with a big caveat. While Oscars is a popular fish at pet stores, they’re not for beginners.
They requires space, and more important, they demand respect. They generate a huge amount of waste, they grow rapidly, and they eats non-stop. This mean that if you have an Oscar, you must be committed to maintaining good water quality.
Many new hobbyists don’t realize how important this is. The upside? You get an almost dog-like companion as a reward.
Essential Care Tips For Keeping Tiger Oscars
Personality and Care Requirements
If you’re looking for something low maintenance, keep looking. The very first must-have consideration is the tank. The smallest I would of ever consider getting is a 55g for one tiger oscar.
Tank Size and Setup
Realistically, seventy five to a hundred gallons make more sense. Tiger Oscars can gets to be twenty inches long or longer. Stunting their growth will happen if they are in too small tank.
It also stress their immune system. The waste need to be diluted and there needs to be enough surface area for gas exchange. Going directly to a bigger tank eliminate the constant tank upgrade every six months.
Water Quality and Filtration
Managing the water, it’s all about volume. Since Oscars is messy eaters, they generates a lot of ammonia. You must has a good filter designed for a bigger tank different than the one you have.
Large sump systems or canister filters is best as they are able to handle high flow rates. Expect to do large water changes (thirty to fifty percent) weekly. Consistent water changes prevents spikes which can kills a healthy fish in a heartbeat.
Feeding Diet and Habits
Most folks makes a mistake when feeding, which means they feed their fish too much. Young Oscars is voracious feeders and they’ll essentially eat until they burst if left unchecked. That doesn’t equate to needing all that food, however.
For best health, young oscars requires a balanced diet consisting off good quality pellets supplemented with some variety such as whole prey and frozen bloodworms on occasion. Variety help them obtain those vitamins needed to maintain bright coloration. Feed them only enough that they’re able to consume in 3-5 minutes.
Anything more than that sinks to the bottom. You’ve fed them too much. The excess will rot and foul the water.
They grow at an amazing pace for the initial couple of year. In a few months a hatchling will be several inches long. To fuel this fast growth, they needs high-protein food.
The diet gradually changes to include more vegetables as they age. Keeping track of their size help you avoid overfeeding, which is a problem with many adult Oscars housed in smaller tank. Choosing tankmates must be done carefuly.
Tankmates and Interaction
Although Oscar cichlids are inherently territorial, they does coexist best with other robust, large fish. Other large cichlid or catfish could also be okay. Smaller community fish will only serve as snacks.
Don’t add a new fish until after your Oscar settles down. Still, monitor for any bullying behavior. A mixed tank is a fragile peace.
All of this effort pay off in interaction. See a Tiger Oscar do tricks for food or follow your hand around the tank. A special relationship develops between you.
It’s a lot of upkeep, but so is a spouse. And just like a spouse, the payoff is worth it. Keep in mind however, these guys has the ability to destroy your day when you forget about them.
Feed ’em and don’t let their water get dirty. Respect the beast and he’ll pay you back.
