my clownfish looks like it died after 2 days of having. him. he's like 1/2" - 1" inch in size. its a 20 gallon tank. anyways i came home lastnight around 4am and i still saw him sleeping. wake up at 12pm then i cant see him. it looks like most of my hermits are having a feast somewhere the tank. cuz i can only see 3 out of 15. . i test my water nitrate 0. im think i should do a 10% water change just to be safe

I would try to find the fish and remove it. Also, how old is your tank?

my tank is 2 months old. it looks impossible to find him in my tank which have so many caves and hiding place. and i was thingking that he so small that my hermit crab feast on him right away?

that's why you have the hermits. don't worry about it.

yeah, with an appropriate CUC you'll be fine.

thanks for the reply guys. ima do 1 gallon water change just to be safe

if he bit it after only 2 days I'd do a full parameter check. Probably pH killed him

oh i actually just did. hehehhe.
amonia 0
nitrite 0
nitrate 0
phosphate 0
ph 8.0
SG 1.024
temp 79
