The Rainbow Shark arrived healthy and active. It’s colorful and keeps the tank lively. I’ve kept it with other peaceful community fish and it’s adapted well. The tank setup was easy to follow and the fish seems to enjoy the algae-based food.

Great addition to my 30-gallon tank. The fish is vibrant and active, though I had to add more hiding spots to prevent it from chasing smaller fish. Feeds well on algae wafers and shows interest in the filter area.
