Hi Jordi, yes, it has been very fast, but let's wait until we see the shrimplets ... still 3-4 long weeks left ...
Fontinalis antipyretica is doing well since the first day in the tank. I have to trim it every 2-3 weeks, fast growing plant taking into account that this is a non-CO2 tank. I'm worried about the summer temperatures here in Majorca island, but I'm working in a cooling system using PC fans and an electronic temperature controller. Let's see the response of both plants and shrimps to the summer heating.
Good luck in your field work, have fun and get Fontinalis for your tanks!
All the best,
Jose
