Hi,
I have excess Endler livebearer males, pairs of Least Killies and maybe some small marble crayfish. Male Endlers in larger numbers are an impressive sight. Least Killies make guppys look big and are livebearers. The can't cross with guppys and females have only one fry at a time. Marble crayfish are an interesting choice, they self-clone so one creates a colony if you decide to do that. The crays will not hurt the fish and I have had them with show quality guppys many times. Marble crays are illegal in some states, so I would have to know where they are going prior to agreeing.
I almost forgot, I have tons of Barking Tree Frong tads in my outdoor pools. You can simply free them once they become frogs. Again, these don't hurt fish at all. You can contact me at
