I also would like to see some changes in the shelf section of my fish tank. For example, there's only room for 1 medication, either ick or fungal treatment. If I have some leftover ick treatment and need to buy fungal treatment, the ick treatment gets deleted, and that's just a waste of money. Similarly, there's only room for one set of eggs at a time, so if I have a set of eggs on the shelf, and I buy another set, the second set deletes the first set. The 4 spaces on the shelf are misleading, it makes me think that I can buy 4 different things and have them on the shelf, but the reality is that there is room for 1 kind of feed, 1 kind of medication, 1 kind of eggs, and 1 kind of growth/hormone supplement. So I wish the next versin of Fish Tycoon didn't limit the shelf space that way.
