Yeah, I have a liquid test kit for all the major stuff. Recently got a small spike in Amonia up from .25ppm to .5ppm. I think Ammo-Lock gave a false reading the next day because my test results were the same.
Guy at LFS
said not to water change on a new tank for a few weeks, and while I do repect his opinion (he's had the shop for 15-20 years and has very healthy fish), the advice I get here is to go ahead and do 20-25% water chaneg weekly. It's been about 1.5 weeks since my last water change. I've topped off with R/O throughout the week, but no water change and I have noted the increase in amonia.
I may as well attempt a change tonight.
Thanks for the 'beacon' reference. Not sure that is it, I will google it. Was at anotehr store this weekend, and came across a very similar fish that was a Lamp Eye Tetra. It was 'close', maybe a cousin, but the Lava Eye was pretty distinct.
