Cardinals are difficult to find in our local market in northern Indiana because most dealers are afraid of them dying off. They really look beautiful and a challenge to keep. So they might be my next challenge!
I bought 10 cardinals together with 10 black tetras. On a 240 L tank that i bought 15 days ago.. and after 3 days all my 10 cardinal diead.. dunno why.. and all the 10 black ones still lives and looks healthy...
My cardinal tetras are dying when it is about lay eggs, their stomach used to enlarge for a week or so then it finally dies. Not just cardinal tetras the same thing happening to platies as well. Any idea
