Used to be called Crenicara filamentosa but I guess their Genus has changed. They are beautiful but bit sensitive. Whatever you do, try avoiding massive water changes with staight tap even with dechlorinator. Aged water and/or clean rain water should be OK provided their water chemistry is w/in reason . I would not tempt to keep them in extreme
pH (very hard and alkaline or very very acidic) upon someone's recommendation who never kept these fish that fish will adpat. Some may but most have not from my experiences with C. filamentosa. I had very good results when kept around 6.6 but dont have to be exact. Just aroung that level w/o sudden changes. Very peaceful Dwarf Cichlid (somewhat shy compared to
GBR) and should be kept in numbers and in well established tank, especially in well planted tank.
How much is Aus $30 in US Currency? Used to be around $6/ea when avail. Unfortunately due to their sensitivity, not too many stores will bring them in, especially wild fish in box lot.
Enjoy them as I have. Good Luck!
