Looks great. I really like the tiger barbs too. Very pretty. I have to ask what is probably a stupid question. Yesterday I picked up a 30g tank similar to yours, similar style simple iron stand. The top of the stand, where the tank goes, just has the metal around the edges, there is nothing to support the stand underneath its middle. Do you put a piece of wood there or what? True, I repeatedly failed math, but I don't understand how a filled tank would require support on only the outer edges.
