hopefully F1 frenata. I am trying very hard to get them to spawn. keeping the pH right at 6.8 dH right around 5 doing 50% a week WC's and setting up a new tank for them (another 75) that is somewhat of a biotope with sand lots of driftwood, rocks, a light flow from a powerhead (240 gph hydor koralia) and some artifical roots. Trying to make it just like the pics of the trinidad rivers I have seen.
