Chromis
In the visible range of the spectrum, many fishes have transparent pectoral fins that are nearly invisible as they wave while swimming. In the UV, however, nearly all pectoral fins become dark and often contrast with a more reflective flank, and while swimming, the moving fin is analagous to a waving flag. Perhaps these fishes are communicating by semaphore! There are consistent differences between species in the wavelength at which transparency is lost, but we haven't been able to find pattern with regard to taxonomy or ecology. Below is shown Chromis ovalis, which has a highly visible pectoral fin only in the UV. [eng]

Green Chromis
These are plankton-feeding members of the damselfish family from the Indo-Pacific region. Several very similar species also occur on coral reefs in the Caribbean and Florida Keys. Except for breeding individuals guarding clutches of eggs, green chromis typically live in schools in the vicinity of branching stony corals. They hover over the corals and feed on small planktonic creatures that drift past, quickly retreating into the protection of the coral branches at the first sign of danger. [eng]

S.A.M.E. Database - Chromis retrofasciata
Typical Chromis species. This is a small peaceful schooling fish that should not be housed with aggressive tankmates. Black-bar Chromis are best maintained in schools, as single specimens rarely thrive in the aquarium. [eng]

S.A.M.E. Database - Chromis viridis
The Green Chromis has long been a staple of the marine aquarium hobby, and is among the most popular of all marine fish. This fish is often sold as a "starter fish", intended to break in new aquariums during the initial nitrogen cycle. Unfortunately, this species really is not quite sturdy enough to survive this, and often perishes under these circumstances. [eng]

Chromis, Green Chromis viridis
The Chromis viridis grows up to 3 inches. The small size will come to you generally 1 to 3 inches; the medium generally 1 to 3 inches; the large generally 1 to 3 inches. The Chromis, Green prefers a tank of at least 30 gallons with plenty of places to hide & swim. [eng]

S.A.M.E. Database - Chromis cyaneus
Possibly the most popular of all Atlantic damselfish, and a long-time favorite among reef aquarium enthusiasts. Like most Chromis species, the Blue Reef Chromis is a very docile schooling fish that should only be maintained in groups. Single specimens typically do not last long. [eng]

Channel Islands NMS: Blacksmith (Chromis punctipinnis)
Blacksmith - Blacksmith (Chromis punctipinnis) live in loose schools which when being cleaned by parasite eating fish, form a tight ball and hang upside down, each fish waiting it's turn to be cleaned. The blacksmiths themselves like to munch on zooplankton, cope pods, crustacean larvae and eggs.(photo: Dan Richards) [eng]

Black Bar Damsel, Chromis retrofasciata
This fish will readily eat all kinds of live, frozen, and flake foods and algae. Finely chopped meaty foods (like brine shrimp) can be fed regularly. It is best to feed small amounts several times a day. In a reef situation they don't really need to be fed very often at all. [eng]

Chromis
Chromis chromis: caratteristica delle scogliere di tutta Italia trova a Miramare sede ideale di riproduzione(le uova vengono fissate al substrato roccioso nei primi metri di acqua) e presenta una spiccata stagionalit� nell'attidudine ad aggregarsi; presenta inoltre caratteristiche eto-ecologiche tanto interessanti da giustificare tutti i lavori che negli ultimi anni di monitoraggio si stanno svolgendo su di essa; lavori che vertono sulle diverse fasi di corteggiamento e su altri moduli comportamentali ancora al vaglio degli studiosi.
