Hi all, Recently I found out for myself that tank size may be veru small. Then I read russian books about fishkeeping, I encounter about the same volumes recommended for keeping the same species of fish. The only difference is that water volume in these books measures in liters, in american ones - in gallons, so, Russian aquariumists use about 4 times less space for keeping and breeding fish then american. And I think Russians are more serious and successfull in the hobby - they do not have Amason river close to export neons and everything, and still neons are one of the most common fish - THEY BREED THEM, and this (and many other things) is not considered any special. As I recall from my experience, 10 gallon tank was considered as a big one, and I have friends who kept and breed A.borelii, angels, barbs, etc in much smaller tanks. Just my 1/2 cent Lilia
