The Rainbow Shark (Epalzeorhynchos frenatum) is a longtime favorite in the aquarium hobby. This fish is not actually a shark at all, but is actually a cyprinid (minnow) that is known for its coloration and activity. It is a very active fish that spends most of its time grazing on algae, biofilm, and other microorganisms in the aquarium. While it is somewhat peaceful as a juvenile, but it becomes much more solitary as it reaches adulthood and can be territorial with its own kind.
 
As stated above, the Rainbow Shark is a generally peaceful fish (although each specimen has its own personality). It does not seem to bother most larger snails, and we have found it to be peaceful with most larger shrimp (such as Amano and Bamboo Shrimp) as long as they are too large to be considered easy prey. The Rainbow Shark is a social fish as a juvenile, but can become more territorial with its own kind and similar-looking species as it matures. Aggression can be kept to a minimum in a larger tank with plenty of territory and cover for each fish.
I would like to sell these as a pair. Even tho they could live in seperate tanks per the aqua bridge they choose to stay in the same tank. I'd also be willing to include the cave I made for them. See the posted photo of the cave.
