I will be asking them to hold it for at least a week and see that they eat. I just got a confirmation from a friend that it will come in their next shipment. Everything I've read tells me that they are very sensitive. Thank you for the heads up on the sixline, I have one in a tank soon to be transferred and I guess he will be left out from the move. It's also good to know that they will tolerate regular temp. I think I will be adding a single male, from what I understand, they don't tolerate their own kinds too well? Also not to mention the heavy price tag for them in my area.
