Search has netted - 0 - in the under $20. range especially the 9.99 ones are a distant past - they are the ones that don't fluoresce under the actinic lights, but none found or I would have bought it. Cheapest ones are around 35 to 39.99.
They are pretty but not amazing, so I am skipping the purchases until I find the cheap ones...the ones of my dreams...at a reasonably high price or just wait. The new SW set up timing isn't quite right atm, I am moving tanks around soon.
Painting walls today actually so we can get the tank area ready for the moves.
On a side note...
Funny a SW "fish" guy responded to me after I ask about if they had any RFA, that they weren't the perfect nems people make them out to be and that they are really hard to culture so the industry doesn't have a good source yet for cheaper prices. (theirs were $79-139)
Thanks for asking. I wish I was building a flower cube too, but not quite yet. Mine will be the ~12G still broken bottom low iron glass tank (which was previously my little SW garden for awhile) - coming soon when I get the bottom fixed. No one close locally for the glass.
I told him I knew of someone who got pics of them spawning and actually has babies now ....he didn't believe me, I am pretty sure he thought I was telling a taLL, TALL tale!!!! His head nodded "oh nice" and his eyes said "NO WAY!!!"
