My water quality was the following when my gf tested it for her beta's:
I've read that EBJD's like slightly softer water than JD so I was going to run the entire system with a bit of driftwood. For the KH, my LFS sold me some alkaline buffer but I don't know about my GH.
If you need other readings let me know and I can get them, gf went and bought a complete testing set for her beta operation.
After reading all the horror stories of people that buy these 40+ dollar fish and then have them die, I'm really tempted to just go simpler for this tank and eliminate EBJD from the option list. I read about some poor guy that bought 11 of these EBJD and only had one live for over a year.
I agree on only getting two, was toying with the idea of 3 but I should wait to see just how overpowered the filtration system I'm building is. Would 2 of GT, JD, or Oscar in addition to a large pleco be overstocked? So 3 fish total at about 1 ft each.
