Redtooth triggerfish has a very different way to swim in the aquarium tanks like most of the triggers they also have fins on the end of its body which is different from other fish. This fish is an easy to keep fish but can be aggressive sometimes towards other tank mates. As soon as we introduce the trigger in the tank most of other tank mates just hide away in the beginning.

Like always it's my day one in the hobby. Always been a hobbyist but never knew would dive so deep in the hobby. I too started with a freshwater aquarium. When I first started saltwater aquarium it just grew on me and I knew that had to do more in this hobby. I am a Post-Grad in Business Administration have worked with Coldstar Logistics, Amazon and Jindal's before jumping completely in the ocean. Other than aquarium hobby I have my interests in travel, digital games and consumer web technology.
