fish dead

woke up this morning and saw my blue goby died. Im not sad bc it didnt do anything it was hiding in my rockwork for a week now. Anyway it was only dead for about 6 hours do you think i need to do a water change or r my other fish in danger. See I dont have a nitrite or nitrate test test b/c i was told u really dont need one once your fish tank is done

 

take him out and you should be fine. you need those tests all the same, your tank is never done as long as there is anything left alive in them.
