Here is it! Some general pics of the setup.
Plants with round leaves are Hydrocotyle leucocephala; it's a great plant because it can grow both in water and creeping outside; it can also bloom, sometimes. On the terrestrial part there are carnivorous plants (Nepenthes and Utricularia): I like them because they are cool, grow well and don't need fertilizer. Bigger pants are in pots that can be removed for care. Toads climb very often on the Nepenthes (particularly to chase crickets..). Water is sligtly brown because of the driftwood (but it's getting cleaner). There's a filter under the cork.
I post also a closeup of one of the guys!
Thank again for comments!
