I have a clown trigger (5yrs old), huma (3 yrs) flame angel (1yr) , lemon peel (5yrs), tusk (2yrs), french angel (8 months), powder blue (1.5 yrs), snow flake (4 yrs) , and gold spot (1.5 months) Oh and a damsel (6 yrs ) and blue line puffer (8 months).
I do 15% water changes every week and a half and have had great success with exception to my Queen angel.
Thank you for your nice comments.
