Chun, Thanks, I will see if I can find an adult pair of sailfin mollies. My pet store only had “Black Mollies” – I wonder if that is the same thing? Regrettably, the dbts have won. It has been a failure trying to get them to eat in the separate feeding tank – they continue to skip the food. So, I am trying food that isn’t too messy in the aquarium where they will eat with the idea that I will do some daily bottom vacuuming with the Python water changing apparatus. The trout chow isn’t as messy as the Reptomin. But, my dbts don’t enjoy the trout chow as much as the Reptomin and won’t eat too much of the trout chow. My problem dbt, the smallest dbt, will only eat about 6 pellets a day and let the rest float around – but, at least it is eating. They do show some interest in Wardleys sinking shrimp pellets – but that is a bottom feeding technique that not all my dbts show an interest in. About the guppies, they live okay in brackish – but after a dbt catches one, it doesn’t always eat it – sometimes it just falls dead to the bottom of the tank. Interestingly, the guppies disappear faster at feeding time. The guppies peck at the trout chow and aren’t watching the dbts. The dbts often get both. ๐ Bob — In diamondbackterrapins@egroups.com, “Chun-Ming Chew”
