50-100 average with just monthly needs, when me and Kel go on a fish binge every 3 months or so it's not uncommon for us to spend anywhere up to 4 or 5 hundred bucks just on new tanks and additions though. The money we have spent on fish and fish related stuff since starting the hobby could have brought us a whole chain of lfs lmao
That's why we have decided to open our own lfs in the next few years and breed alot of our own stock. Healthy, rarer specimens (and all the commoner species as well) for lower prices is our way of thinking. Customers would be happy because they are getting better fish for better prices (some of which are extremely hard, if not impossible to find in any lfs over here - a couple of which I know for a fact that suppliers cannot get hold of, therefore impossible to find), we would be happy because we would be getting alot of business and the satisfaction of knowing we are helping alot of problems in the fish industry these days, pretty much everyone would be a winner, except for the other sub-standard lfs that would be driven out of business (not that they should be in business to start with).
