Thread: Urgent! Urgent! Fish Dead?

Difficult to answer without more details.

What kind of tank do you have them in? Was it cycled before the fish were added and how long has it been set up? What, if any, tankmates are there? Were there any symptoms before and after the fish died? How were the new fish introduced? Too quick can send them into shock.

My thoughts is there's something wrong with the tanks water and a full spectrum water test is in order.

Yesterday my sister bought 3 dwarf rainbows she got them home safely and they settled well but now when we woke up this morning the smallest one was dead and just 2 minutes ago one of the males died what to do what is wrong? Will the other die? My sister is sobbing her eyes out.
I have had it tested and everything it all came back ready for fish everything has been working fine and there was nothing else in te tank just the three rainbows?
The water temp is 26 and through research i hae found out that is perfect.
