1 small marine (~50 l)
1 medium marine tank in the future (400l)
4 fresh water tanks (40-130l)
11 fresh water breeding tanks
We keep Guppies mainly, Albino Corydoras (they started breeding in one of our tanks but after ~150 babies, it seems they have stopped now), assasin snails (they keep reproducing), Honey Gouramis (they started breeding as well, but the babies did not survive... better luck next time) some danios and tetras, Red Cherry Shrimps.
