Nano problems

[NorCalcorals]

Hello everyone. I have a 240 display and a 450 frag tank for the business. I also set up a 29 gallon biocube. I have the sunbrite led lighting over it. My corals in it are doing amazing. Some rainbow acans, maxima clam, lobo, and tricolor rose anemone. Every time I put fish in they seem to die. I test the water the levels are good. Temp seems stable everything seems OK. I go to sleep and in the morning all the fish are dead all the sudden. Clowns wrasse gobies etc. Ive tried this three times now.Ive thought of a pest, temp swings and other problems. Any ideas would be greatly appreciated I do not want to keep killing stuff and my girlfriend wants fish in the tank.

How long has the small tank been set up? Ive always had problems keeping fish alive in tanks where the rock has not been live for more than 3 months, at least.

I used rocks out of my established tanks. I test the water regularly and everything seems good. They just all die over night.

that is very strange......do the fish show any visible signs of anything? rapid breathing? lethargy? erratic swimming?

 

[NorCalcorals]

not that I have noticed. And they all seem to die on the same nights. I have tried a couple of different times and the fish are fine until one night they just die. I haven't noticed any temp swing or anything that would lead me to believe something is wrong.

they die on the first night? with that rapid of a demise, I'm wondering if it could be low oxygen? or stray voltage?

I was just thinking stray voltage myself fishroomlady
