anyone have any luck with lillys for freshwater tanks I bought mine at petco and no white fuzz or mold. I was told to take them out and toss them if I saw any of that on them. So I think that's good also I heard that these bulbs grow faster with warmer temps. Is that true any advice would be good they are also bured 3/4 of the way in the gravel. they have also been in the tank for about 4-5 days now thanks.
