Splash Tetra (Copella arnoldi)
Splash Tetras are a peaceful species, are indeed beautiful and fascinating little fish. They are easy to keep and a delight to breed. The only disadvantage is that they are pretty scarce and rarely offered for sale.
Splash Tetras are shoaling fish; therefore, they are best maintained in good-sized groups of at least six to ten individuals. Due to their relatively small adult size, you must take care when it comes to choosing their tankmates. These Tetras are easily intimidated by larger, more boisterous fish, and you should not house them with anything that would consider them a snack. Good companions would include smaller species of Dwarf Cichlids, Pencilfish, Corydoras Catfish, Killifish and other small blackwater Tetras.
Splash Tetra are a small, slender fish with an olive-brown body and a whitish belly. They have a relatively large and upturned mouth with acutely pointed teeth. They display a dark spot on their dorsal fin with a whiteish-pink border and a dark band from the snout to the eye, which can continue through to the operculum.
Their caudal fin is profoundly forked, with the upper lobe being more extensive than the bottom lobe, which has a scarlet flash. Their adipose fin is absent, and they use their large pelvic fins when spawning. In desirable water conditions, the upper half of the iris will develop an iridescent orange colour.

In the home aquarium, the Splash Tetra will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.
Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.
It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.
This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.
It is relatively straightforward to distinguish male from female Splash Tetras. The males usually are larger than females and have longer fins which are more colourful, with red and black outlines. In addition, when males are in spawning condition, a thick dark band may extend posteriorly along the body from behind the opercle.
