I'm not sure about tanked, but on my ai hydra 52 I can set chance of clouds and lightning, and the intensity. I turned the lightning off though because it's rather bright and wakes me up lol.
I'd imagine a lot of higher end leds have those features, but I can only speak for the ai hydra.
Okay thanks I'm upgrading from a 29 to a 110. I can't find any coral compulsion 120p to match the one I have so I'm gonna just upgraded for my this tank. unless anyone knows anybody selling a coral compulsion
