About a month ago I moved all my LFS feeder ghost shrimp from my planted tank to the turtle tank after I lost a couple of RCS and Amano shrimps. In hindsight this may have been a bit of an over reaction, and I'm thinking of moving the surviving ghosts back as one of them is heavy berried. No worries though, the turtles are rarely fast/interested enough to catch the ghosts.
Back to the plant tank,it is 40gal, 80w of high output light, no CO2, no ferts, pretty densely planted, plants growing well. It is stocked with ~18 RCS, 10 Amano, 2 Caridina gracilirostris, 4 close Amano relitives, and ~15 guppies. The plant tank serves as a natural filter/scrubber for the turtle tank. The water is circulated between the plants and the turtle tanks with a little 250gal/hr pump. It does a pretty good job, at keeping NH4, NO2, NO3 in check with bi/tri-weekly water changes ~25% of the total system water(~100gal). Recent tests give me a NH4~0ppm, NO2~0ppm, NO3~10ppm, pH 7.6. I keep the temperature at around 78DegF.
To my surprise I seem to have had some luck in breeding the ghosts in the plant tank! A few days ago I saw what looked like was a tiny shrimp swimming about. I've been able to take some super macro shots of at least two of these little guys. One of the little ghosts is about twice the size of the other. ~3mm&~7mm long

So since it's been over a month since all the adult ghost's were moved, the larva that resulted in these guys survived for a month in a tank with guppies? It's doubtful that the larva would have been able to make it through the gravel prefilter, pump, if they were born in the turtle tank.
Any ideas?
Thanks!
