Lantern Basslet
Lantern Basslet
Takes a great aquarium addition given the correct aquarium mates. The Lantern Basslet is attractive and hardy, but may be harmful to some smaller fish and ornamental fish. Growing to only three inches in length, it is a fish of appropriate size for all but the smallest of aquariums. If more than one is to be present in the same aquarium, it is recommended to introduce them at the same time. The Lantern Basslet spends its time swimming actively and occasionally digging in the substrate using its somewhat elongated snout. Its deep red, marbled body is accented by a yellow lateral line running down the body in healthy specimens. A bright white may be visible at times on the ventral fins.

FAQ
What are the ideal tank mates for the Lantern Basslet?
The Lantern Basslet is best kept with larger, more robust fish that can withstand its occasional aggression. Avoid small or delicate species that may be harmed by its digging or nipping behavior.
Is the Lantern Basslet suitable for a community tank?
It can be suitable for a community tank if the other fish are large enough and not particularly sensitive. Introducing multiple Lantern Basslets at the same time is recommended to reduce aggression.
How does the Lantern Basslet behave in the aquarium?
The Lantern Basslet is active and spends much of its time swimming. It will occasionally dig in the substrate using its elongated snout, which may disturb the bottom layer of the tank.

The Lantern Basslet is a striking fish with a beautiful red and marbled body. It’s active and adds a lot of movement to the tank. I introduced it with a few larger fish, and it hasn’t shown any aggression. The yellow lateral line is very noticeable in good lighting.

It’s a nice addition to my 20-gallon tank. The fish is hardy and stays active. I did have to remove a small shrimp that was getting nipped, but otherwise it’s peaceful with the larger fish.

Looks great in the tank. The color is vibrant, and it swims well. However, I noticed it digging in the substrate, which caused some sand to shift. I’m not sure if it’s a problem or just natural behavior.
