Hello, I have recently gotten a 75 gallon and was about to begin the process of designing it. I have been researching and really enjoy the looks and habitat of the ameerega Pepperi and Bassleri. I like the idea of incorporating a stream/pond and mimicking where they would be found in nature. My first question is how available are these in the hobby and how much do they typically cost? I haven't seen many ads as of late of anyone selling any. Secondly are there any other pdf's that are found in a similar ecosystem that could be an alternate shoice?
