I am in Mount Wolf (near emigsville exit of 83).
Right now for dwarf cichlids I keep apistogramma cacautoides orange, triple red, and wild. I also have apistogramma viejita 2's, apisto baenschi, and apisto aggi tefe blues. I keep them in a relatively neutral tank environent through the use of almond leaves. Typically, the pH in those tanks is around 7ish, gh 6, kh 6ish. My tap water has a pH of 7.8, gh 10, kh 12, tds of about 180 so while its not easy to manipulate, the relatively low TDS works with me. All of my species are spawning in this adaptation of tap. I do not pretreat their tap water, but just use natural means of adding tannins to adjust things for them. I also have some l. dorsigera, though they have not spawned for me yet.
I doubt I would carry gbr's as I prefer the wild type to the line bred morphs. The wild rams i brought in a few months ago were staggeringly beautiful though fragile until full acclimated. They sold out quite quickly and once it warms up, I will likely bring in more.
I am about to start my power seller account here on this forum as well
