Fish arrived healthy and stayed active after a week. The feeding instructions were helpful. I noticed the red color is very noticeable in my 10-gallon tank. Good choice for a small, calm fish.

Perfect for a beginner aquarist. The fish is small, peaceful, and adds a nice visual appeal. Water conditions are well explained and easy to maintain. I’ve seen no aggression with other tank mates.
