Are kissing gouramis and Silver Dollar fish compatible?

No, kissing gouramis are not compatible with silver dollar fish. Here's why:

1. Fin nipping: Kissing gouramis are well known for their fin nipping behavior, especially when not provided with enough space or suitable tank mates. Silver dollar fish have long and delicate fins, and are therefore highly vulnerable to fin nipping. The constant nipping of their fins by kissing gouramis can cause stress, pain, and susceptibility to infections.

2. Aggressive behavior: Kissing gouramis can exhibit territorial and aggressive behavior, particularly during breeding seasons. They may harass and chase other fish within their territory, including silver dollar fish. This aggressive behavior can cause chronic stress to silver dollars, affecting their overall health and well-being.

3. Feeding Competition: Both kissing gouramis and silver dollar fish are omnivores with similar diets, meaning they'll compete for the same food sources. As kissing gouramis can grow larger, they might outcompete the silver dollars for food, leaving the latter malnourished or underfed.

4. Compatibility in Water Parameters: While silver dollar fish prefer slightly acidic water with a pH between 5.5 and 7.0, kissing gouramis prefer neutral to slightly alkaline water with a pH of around 7.0 to 7.5. The long-term compatibility of these species in terms of water parameters can be problematic, as it might be difficult to maintain water conditions that suit both species.

To ensure a peaceful and harmonious environment for both species, it's best to keep them in separate aquariums to prevent any potential conflicts or stress-related health issues.
