New tank

[bribo12]

I moved the damsels to my older tank for now and I put my other damsel in my quarantine tank because I can't put bother together in my other tank or they will pick on my tang and clown fish but I moved the damsels for now so I can re cycle the tank and see if I misses something when I allowed my daughter to help it's her first tank but just not sure what went wrong

Sounds like that's the right move.

I don't think your cycle ever finished. You added 3 fish as well which is a heavy bioload for such a young tank. You will need to do water changes as needed to get ammonia back down to 0 until the cycle completes

We'll I never exactly placed the third in my tank my folks wanted the black one I I just got so it went in there's but I kept the dark blue and yellow to finish the cycle process

You barely made it halfway through the cycle process. That's your issue, just re-cycle the tank using the correct process.
