Table 1. Invasive ornamental fishes in Peninsular India and their possible impacts

	Species	Trade name	Native to	Possible impacts
1	Poecilia reticulata	Guppy	South America	Resource competition, spread of pathogens, egg predation, larval predation
2	Xiphophorus maculatus	Platy	South America	Resource competition, fin nipping, agressive nature, tadpole predation
3	Xiphophorus helleri	Swordtail	South America	Resource competition, fin nipping, agressive nature, tadpole predation
4	Trichogaster trichopterus	Three-spot Gourami	South East Asia	Opportunistic carnivore, territorial & aggressive
5	Pterygoplichthys multiradiatus	Sucker Catfish	South America	Disrupts food chain by overgrazing, egg destruction, resource competition, bank erosion, shore bird mortality, damage to fishing gear
6	Osphronemus goramy	Giant Gourami	South East Asia	Resource competition, opportunistic carnivore, carry pathogens
7	Amphilophus trimaculatum	Flowerhorn	South America	Predatory fish
8	Pygocentrus nattereri	Red Piranha	South America	Predatory fish, fin and scale eating, mutilating other fish
9	Carassius auratus	Gold Fish	East Asia	Causing algal bloom, causing turbidity, eats eggs, larvae and adults of native fish, transmits pathogens and parasites, depletes aquatic vegetation and reduces spawning sites
