lol gday Greg,
From collecting brood stock, wild, to fully trained to frozen was only days, they are great feeders.
I honestly recon as they are a bit on the booring side, very beautiful, undeniably, but they do nothing.
Leafys are ambush predators, so all the buggers do all day is drift around and act like a piece of broken off seaweed, Weedies on the other hand are far more active, and IMO just as lovely, because of the coloring.
Leafys are very hardy, weedies tend to be quite a bit less, the only real problem with leafys is they really spook easily, and flashes such as camera flashes scare them badly, and if there is a lightning storm, this can easily kill them, always have provisions for exclusion of outside light, and in times of possible lightning, run night lights, sort of like full moon.
Leafys do not like light, soft is far better, remember they are a deep water fish and so light is somewhat muted, same with weedies.
I have found leafys at around 20', but that was rare as, usually both are below 60 or so feet.
That is no rule, just observation.
Another thing, Leafys are very spiky, and the spikes are needle sharp and will puncture skin easily, rotten buggers, guess who found out the hard way.
