tank disaster

[rickyg78]

Hello, I recently got a 36 gallon bowfront about 2 months ago, the guy gave me everything I needed except the filter but I had filters from my old tank that I kept running on my 75 to make sure that the bacteria wouldn't die. Anyways, I did a water change last night and everything seemed fine but all the mbunas passed except 1. I don't what it could be. Filters were cycled,water was dechlorinated, temperature was right, ph,nitrates,nitrites all were in good levels. What could have happened

Did you clean the new tank?

 

[rickyg78]

Yes, whiped it down with a moist towel.

Sounds like the tank may have been exposed to something possibly prior to coming into your hands. I would recommend stripping it all down completely and starting again after giving everything a very good clean. Can the one remaining mbuna be housed elsewhere while you do this ? Decor and substrate may have to be thrown away and start from scratch.

Sorry to hear.
I always test the water before and after a water change. Maybe something got in the tank?

Im not even sure. Everything seems to be in good measure. The I have coral substrate which i don't know if it affect this. But I think ill start the tank all over

Coral is fine for Cichlids to keep the PH up. I don't see that as an issue.
I assume you rinsed the coral before adding it. still, it would just make the water cloudy if you didn't.
There was another thread of someone losing all fish all of a sudden.

Anyway, I once lost all my fish to ick. I shutdown the tank, left the gravel and decorations outside under the sun for a few days and started all over again.
I did not want any traces of ick in this case.

Good luck on your new start.
