The Red Soldier Fish arrived healthy and active. It has been in my 10-gallon tank for two months and stays near the surface, showing good color. Easy to care for and adds a lot of visual interest. I recommend it for beginner to intermediate aquarists.

The fish looks vibrant and moves around the tank with energy. I’ve kept it with a few tetras and it doesn’t seem to stress them. Water parameters are stable, and the fish seems to adapt well to the environment.

Great addition to my aquarium. The red color stands out well in the tank. It’s active but not overly aggressive. I’ve noticed it’s more active during the day and rests at night. Very satisfied with the purchase.
