I initially had one Clown, within a week I bought another, it died a matter of hours later, I believe just due to stress and such.
replaced that clown with another, it died by the morning but it looked damaged so I assumed it was attacked because I saw them at it before.
It's been about a week or two since then, my clown just started acting funny for the last few days, being withdrawn, breathing oddly etc..
Last night it just started settling onto the sand, looking weak.
It never had been a social fish, it's only ever really stayed in the corner rarely swimming out.
