I am considering getting some of these guys for a Tanzanian biotope enclosure, but had some more questions. I was looking at the ad here: kingsnake.com Classifieds: REED FROGS:GREEN GLASS, ARGUS, GOLD SEDGE, RETICULATED AND MORE. and it looks like two types are sold.

The gold sedge which look like this: Hyperolius puncticulatus_2 on Flickr - Photo Sharing!

and the reticulated which look like this: Spotted Reed Frog (H. puncticulatus) on Flickr - Photo Sharing!

Are these two variations within the same interbreeding population and should be mixed in captivity, or are they different subspecies/morphs that don't interbreed in the wild and should be kept separate?

Also I know they can be loud but just how loud are they in comparison to say.. Dendropsophus ebraccatus? Trying to compare their call to a frog I have so I know what I may be getting myself into..
