Beautiful fish, Linka. Sorry about your loss. It would have me concerned too if a fish that seemed perfectly healthy dropped dead. I hope you don't have more problems crop up and it just stays a mystery. I guess not knowing is bad but finding out something awful is worse. Good luck.
U are quite right. Not knowing is bad, but finding something awful is MUCH worse.
My other fishes seem healthy, but I will watch out for a few days. Just to be on the safe side.
Took a water change yesterday but that should not kill him so I don`t know. Took another change today and with two days of water change 3-4 og my Pseudotropheus Acei Ngaras are holding so that male sure gets his grooove on... :lol:
