Added a Redtail Botia Loach to my 10-gallon tank and it’s been active and peaceful. The red fins stand out well in the planted area. It helps clean up leftover food and snails. I keep it with two others of the same size and they school nicely.

The fish is colorful and active. I noticed it spends most of its time near the bottom. It doesn’t seem to stress other fish, even though it’s semi-aggressive. Good for a community tank with similar-sized species.

Great addition to my aquarium. The red fins are very noticeable. It’s a scavenger and keeps the tank clean. I’ve kept it with other loaches and they get along well. Easy to care for and looks great in the background.
