I do think calcium may be my problem as some of the shells seem quite weak. How would I increase the calcium safely?
daveedka said:I'm sorry but I can neither believe this or picture it. If there was enough food and calcium both in the tank to create this scenario, then the snails were definately not the cause of the dead fish. If anything they helped prolong the fish's life span in some way or another. The amount of calcium it would take to grow a colony of snails that dense is not a trivial matter by any stretch. The amount of food that needs to be present to get snails to produce that well is not trivial either. So the idea you are describing could only be achieved with an extremely heavily fed and fouled tank, with high calcium additions. I have tried for quite a while to create massive quantities of snails. it is difficult to do in clean tanks. I don't keep dirty tanks as a rule, so I will admit I don't know what can be done in that regard, but I still doubt there would be enough calcium. Even in some of the nastiest tanks I have seen there is a limit to snail reproduction.
