earthandanimals: These fish are dye injected. I urge you to stay away from them as the process can be stressful for fish and can lead to health problems. It is not right and an end should be put to it asap.

fishesnstuff: fuck-yeah-aquascaping: Never ever buy artificially pigmented fish. This is torture. My work got some tattooed balloon mollies in our fish shipment last week. As soon as I pulled the bag out I was livid. I went up to my manager and said, “Really? Why the hell are we getting these?? This is pure torture for these fish!”  I’m putting in my two weeks today. Pretty? Maybe so, but these fish have to be dipped in a chemical to strip them of their slime coat, injected with paint, and dipped in another chemical to irritate the skin to regenerate their slime coat, all while out of water. Not only that, but the paint fades over time. Artificially coloring fish is animal cruelty. NEVER buy any painted fish. Besides, the natural coloration of many species outshines painted fish any day.

ichthyologist: Drought Resistant Killifish Eggs Native to the floodplains of Africa, the killifish of the genus Nothobranchius are subject to seasonal weather fluctuations. The fish must quickly grow to adulthood within one wet season, when their ponds are full. If they fail to do this, they will simply dry when the rain stops without producing the next generation. Their eggs have the amazing ability to withstand being dried out. They lay in a state of diapause, resting periods when development ceases, over the time when their pools are dry. When the rain finally comes, a series of biochemical messages causes the eggs to resume development. These young fish must race to mature and breed before their pools dry out again in a couple of months. (Nothobranchius rachovii pictured) HelixPermit on Fickr

ichthyologist: Endler’s Guppy (Poecilia wingei) The Endler’s Guppy is found in a few lagoons in Eastern Venezuela. The fish is in danger of becoming extinct in the wild due to habitat destruction.  This species is closely related to the common guppy (Poecilia reticulata) and the two species readily interbreed, although this is discouraged as it dilutes the genepool.

ichthyologist: Air Breathing Labyrinth Fish Freshwater fish of the family Anabantoidei have a specially developed organ that allows them to take in atmospheric air. The labyrinth organ is a modified gill arch that allows the fish to process gaseous oxygen. Labyrinth fish are found in warm, slow moving waters of Asia and Africa. These habitats are low in dissolved oxygen. The labyrinth organ allows for the fish to exploit the ecological niche that other fish cannot survive in.
