My male platy has been acting rather shy recently. He's been hiding out in a kind of mini cave under a sunken ship decoration for almost the entire day. All my other fish seem normal, but i checked the water parameters anyway an they were
NH3 0,
NO2 0,
NO3 20. (the tank is fully cycled)
He is in a 33 Gal with 6 sterbai corys, 5 Zebra danios, 2 male guppys and another platy.
When i fed them this morning he came out to eat but soon went back in his cave.
Do you think that something is up, or could it just be his personality?
(i havent noticed any strange behaviour from the other fish, and he looked healthy enough when he eat this morning)
