How good are leopard ctenopomas at catching small, fast fish like mosquitofish? ... Could this continue without stressing the mosquitos to death? There's a good bit of tannins and stirred-up clay (experimental mixed substrate + cories) in the water ...
... I would think with them being ambush predators, they would catch prey more often with more plant/leaf litter cover to ambush from ...
... But observing the leaf fish hunting, it was strictly a wait and ambush approach. He never chased anything down.
would not be efficient at all in catching small, fast fish like mosquitofish. Gambusia
are the terrors of the aquatic world, just ask or Aussie members. Gambusia
getting stressed to death by Ctenopoma
? Never. More likely the other way around, they may very well gang up and shred the larger fish piranha-style. See this vid of them shredding a frog to the bone youtube.com/watch?v=TEUHVBvyD48 1:15-1:45 even if no comprendéis español the vid is still worth watching.
Having "a good bit of tannins and stirred-up clay (experimental mixed substrate + cories) in the water" sounds odd. Tannins are acidic, clay is alkaline. In which direction are you trying to go? Also note that Ctenopoma
thrive in acidic water whereas Gambusia
thrive in alkaline.
WaterLife & frog111 are correct, they're ambush predators, need cover to ambush from, it's strictly a wait and ambush approach, no chasing. Labyrinths, including Ctenopoma
, by evolutionary design are neither strong nor fast swimmers.
