Red Tail Sharks (Epalzeorhynchus bicolor) and Opaline Gouramis (Trichogaster trichopterus) can be compatible tankmates, but there are a few things to consider before keeping them together.
Size and Temperament:
Red Tail Sharks can grow up to 6 inches in length, while Opaline Gouramis typically reach a maximum size of about 4 inches. This size difference can sometimes lead to aggression from the Red Tail Shark, especially if the tank is too small or there are not enough hiding places for the Gourami.
Red Tail Sharks are also known to be territorial and aggressive towards other fish, particularly those with similar body shapes or colors. Opaline Gouramis are generally peaceful fish, but they can become stressed if they feel threatened or harassed.
Water Parameters:
Red Tail Sharks and Opaline Gouramis have different water parameter preferences. Red Tail Sharks prefer slightly acidic water with a pH of around 6.5-7.0, while Opaline Gouramis prefer neutral to slightly alkaline water with a pH of around 7.0-7.5.
It is possible to keep these two species together by finding a middle ground in terms of water parameters. However, it is important to monitor the water quality closely and make adjustments as needed to ensure the health and well-being of both fish.
Tank Size:
The minimum tank size for a Red Tail Shark and an Opaline Gourami is 30 gallons. However, a larger tank of at least 50 gallons is recommended to provide enough swimming space and reduce the risk of aggression.
Hiding Places:
Providing plenty of hiding places in the tank is essential for both Red Tail Sharks and Opaline Gouramis. This can include live plants, driftwood, and rock caves. Hiding places allow the fish to feel secure and reduce stress levels.
Diet:
Red Tail Sharks and Opaline Gouramis have similar dietary needs. Both species are omnivorous and will accept a variety of foods, including flakes, pellets, and live or frozen foods. It is important to offer a varied diet to ensure both fish receive the nutrients they need.
In Conclusion:
While Red Tail Sharks and Opaline Gouramis can be compatible tankmates, it is important to carefully consider the factors discussed above before keeping them together. By providing a suitable environment and meeting the needs of both species, it is possible to create a harmonious and successful aquarium.
