So first time with planted tank, and have been slowly adding plants for the last couple weeks. I have been buying mainly tissue culture type plants to avoid pest snails and haven't seen any so far on java ferns, rosette sword and anubias so far. I did buy a crypt out of a tank at a store the other day and will be getting around to planting it today or tomorrow. It is in a small pot with the rock wool, looks very healthy. I looked closely at the tank it was in, as well as the other plants that were in there and didn't see any adult snails moving around (tank glass wasn't super clean or terribly well lit so I can't say for sure 100%). I did see a couple fish swimming around in the plant holding tank so it wasn't just water, it was at least cycled. I asked an employee if they knew if there were snails in that tank, and we both looked for a few mins and couldn't see any, but the employee said she couldn't be 100% sure there weren't snails in there. I took a chance and brought it home. I am hesitant to dip in bleach as I know crypts are prone to melt, and am wondering if I can get it to not melt too bad since it has been in water for some time now. I have had it in a glass vase submerged in de-chlorinated water to see if I could see anything going on in there. i am trying to avoid introducing pest snails at this time so I have a few questions. Is my holding the plant in the vase doing any good at all? I haven't seen any snails, and I assume that if there were any I may have seen them moving around by now? When I pull the plant out of the pot to break it up before planting would eggs be visible to the naked eye? would rubbing down each leaf do any good to remove anything? If I take a really good look at each plant-let would I see spots/eggs and be able to address? or am I still flipping a coin by putting this in my tank? I plan on looking it over very closely when I am getting it out of the pot and breaking it up. Is this thing going to melt anyway and should I just dip it to be safe? or will that kill the plant? Thanks for the help.
