I've seen the glassfish often in NY, usually at Asian-owned stores. Unfortunately, all of them are dyed.
Amanos are FW. Their babies float down the stream to brackish areas and develop, then when they are strong enough return to FW.even though I'll have a beach like set up, I am not considering mudskippers because I know they are too large for the tank. (the tank is a 15 g, with 10g of water..)
aclimation won't be a problem, as I am starting the tank freshwater and going to transition to brackish over a month. it will be very mildly brackish, just enough for the inverts to have what they need. BBgobies are really attractive to me, but with inverts I'll end up with a tank full of bottom dwellers hiding all the time. I may go with just glass fish, but haven't even seen them locally. I guess I could get 1 guppy, but I'm not interested in breeding them. if any breeding happens in this tank, it will be amanos.
