The Age Of Aquaria

From the looks of these USGS Non-indigenous Aquatic Species Alerts (new reports of discoveries from May 2006 and earlier), Puerto must be turning into one giant fish tank:

• Rosy barbs (Puntius conchonius) [so common, they are now being used as bait fish]
• Congo tetras (Phenacogrammus interruptus)
• Tiger barbs (Puntius tetrazona)
• Red devils (Cichlasoma labiatum)
• midas cichlids (Cichlasoma citrinellum) [also here]
• Rio Grande cichlid (Cichlasoma cyanoguttatum)
• Convict cichlids (Cichlasoma nigrofasciatum)
• Sailfin catfish (Pterygoplichthys disjunctivus)

For more information, check out this page from MongaBay - it's a list of known fish species in Puerto Rico, marked as native or non-native, with links to their FishBase species pages. Fifty-six percent introduced (30 species) - very impressive!
