Tank #2 Update
About three weeks ago, four of my harlequin rasbora commited a suicide by jumping out of this tank, after seeing my ugly gf face hahaha...(just kidding darling)...but really for no clear reason one morning I found four dead harlequin rasbora on the floor!...I have checked all water parameters and all seem fine..
Anyway, I decided to keep Cardinal tetra this time. So I bought ten. Acclimated them slowly, for about an hour. Before that I do 1/3 water change. Over the period of one week, I lost 6. So heart breaking and puzzled at the same time...again I checked all water parameters and all seem fine.. anyway, I bought another 10 cardinal tetras. This time I do 1/3 water change and dose water conditioner according to the instruction and acclimated them for over an hour slowly. Up until, now all 14 cardinal tetras are doing fine...
Regards
