Easy Transaction Healthy Fish
Very happy with this dealer. The transaction was very easy and all the fish came alive and are thriving.

A bit finicky, but worth it.
They may come to you smaller than anticipated and may need powdered food or baby brine shrimp to eat until they grow. They also are a timid fish and benefit greatly from the presence of dither fish (I have 2 male endlers), lots of dark plants, and dark substrate. Between that and regular feeding of live foods, the colors can really pop and their personalities really come out.
