Betta fish

On the one hand, it is a really desirable fish that even novices would like to acquire. However, it is difficult for novices to choose since it requires a lot of maintenance. First of all, because to their distinctive appearance, everyone wants to possess one or two Bettas. Although they come in a variety of colors, the fin at the rear is what you should pay the most attention to when you look at them. Compared to the majority of the other species on this list, this covers half of their body, giving them a highly distinctive look.

However, being among the most attractive fish has a cost: they don't get along with people very often. Bettas seldom get along with one another in general. Because of this, caution should be used while adding new species to the tank. The Black Tetras, Catfish, Croacking Gouramis, Rasboras, and Poecilias could make suitable tank mates.
