I have a lid with a small opening to drop food in and an opening where the filter is. The water is down about 2.5 inches from the rim of the tank. I clean the tank about once every 5 weeks or so and I clean the filter once a week. I feed the snails a balanced diet of calcium chips, snail cookies from crayfish empire,algae wafers and snail mix #4 from aquatic arts. I just got a gallon of spirullina this week so I'm going to try to make snello with that, green beans, the powder calcium and tropical flakes. I also intend to blanch cucumber and zucchini. I put in about 5 mL of liquid calcium in every week and a half or so. I have plants in the tank to filter out some of the nitrates and such. I have the heater set to about 76. I have seen them mount each other a couple times this week but it's never longer than a couple of minutes. Just this morning, a blue was mounted on an ivory snail. Does anyone have any tips on another way to help better take care of them so they are in good health to even lay clutches? BTW, I took the 2 out of the breeder box. I started to have anxiety about them not having enough room. They weren't in the box a half of a day. Lol
