Finally I decided last week to sell my nano-reef. I decided to install it to mantein seahorses, but I never got that they survive. I tried only with Hippocampus Kuda but the result was always unsuccessful. Here you can see a picture of my nano:
Lastly, I had in some frags of my reef and some gobies (Nemateleotris Decora and Gobiodon Okinawae). Now, my hope is to install in the close future a bigger nano, about 100l, with the appropiate equipment to mantein this type of animals. May be the mistake was to try with young seahorses, may be adult animals are easier.
More in the next chapter... ;-)
