I got 2 teacups coming tomorrow. I have read a lot about them. My parameters have been perfect for about a week now (ammonia was at .25 last night) so I'll just do a water change tonight and get the gravel out of their new home. Anything I should be expecting? I'm going to mix the waters very slowly, I have blood worms and krill to feed them. (they are at 4-5") they have a 500 gallon pond in the basement I will move them to as soon as I build a filter and cycle it. I have never owned a stingray before but I have wanted them for almost a year and I have been researching them most of that time. I believe I'm ready. I'll post pictures tomorrow
