Your nitrIte needs to be 0. Do you have readings for ammonia?

Is the tank established or new?

 

[fish_keeper2]

how big is the chinese algea eater. when full grown they can get real aggressive, if this one is full grown it could be killing your fish. if not it has to be with the water so well also need to know the ammonia levels. nitrites need to be 0 as has been stated all ready

Neon tetra's are no good in cycling tank they need a mature tanks of six months,as very fragile tp poor water quality, the chinese algae eater it far way to big for a 10gal will become aggrressive and they are one of the worse plecs you can keep, i would consider taking it back,plus a nitrite reading above 020 is toxic to fish, and none of those fish are hardy to cycle a tank with.
