Last time I was in a local pet shop some new, bright fish caught my eye. I recognized their body shape, but the colors…I don’t belong to those who support the idea of genetic modification of fishes, but in this case the fish really deserves to be spoken about. So, let me introduce you a GloFish!
Cherry barb (Puntius titteya) is a small and nice tank fish, one of the most popular barb species.
The serpae tetra (Hyphessobrycon eques) is a tropical freshwater species which are sometimes referred to as jewel tetra, callistus tetra. This is an overwhelmingly beautiful fish that looks like a small moving flame in a tank. You won’t be able to take your eyes of serpae tetras school in an aquarium.
This is a schooling fish and it feels better in a school. There should be at least 6 fishes in it and the fish can be kept together with some other fishes of the same size and activity level. The drawback of keeping tetras in a tank is their a bit troublesome temper – they can haunt and nip the fins of more slow tank mates.
The red-bellied piranha or red piranha (Pygocentrus nattereri) — is a predatory fish kind and it belongs to Serrasalmidae subfamily, which is one of the most well known kinds of piranha.
These fishes live in a huge schools that spend the majority of time looking for a prey. The fish is rather gluttonous, therefore it can live only in the waters rich with fish.
More often red belly piranha can be encountered in some shallows, in the depth and in the muddy waters. Again, as one of the most known piranha kinds, it has a reputation of a freshwater predator, that is dangerous both to human and animals.
