I dont know about this – but … I would say, I definitely avoid those really big black mosquito larvaes, – they can be really really big and nasty.
But theres no problem with most sizes, but the really big one … I would be careful.
Of course it also depend on what fish you feed, – somehow a chokolate gourami should be able to handle it ??
I am always a bit cautious with my live food, – I know most people dont seem to worry, but I have experienced – as you – suspiciously connected death with feeding with mosquito larvaes, mostly the white ones, –
Maybe fish get carried away because they are so attractive and simply overeat… that might be a possibility too ??
