Who will ship to marine fish and corals to spain?

Good luck finding anyone willing to deal with the paperwork. Assuming you can find someone desperate enough to send you fish, by the time you pay for freight, you will probably spend much more than you would have if you just bought it in Spain. When you get there, try to go to a German fish store. Those guys put us Americans to shame when it comes to fishkeeping.

on your first tank, i could advise going with less difficult to maintain corals and fish. some simple corals are mushrooms and softies (leathers, Kenya tree, megastar polyps, Anthelia, and so on). they do no longer require as lots mild to thrive and are much less finicky approximately water situations, yet will nevertheless seem intense-high quality and reproduce on your aquarium. some cautioned fish first of all could be clownfish, cardinalfish, a gramma, a watchman goby, and doubtless a hardier dwarf angel like a flame or an argi. stay sparkling of the particularly comfortable fish like butterflyfish, mandarins, and various the bigger angels and tangs till you have gotten the tank extra settled.

Your best bet is to look around online when you get there.
