I don't know why
But I have had trouble with keeping my clown fish alive.
I have a yellow tang, two chromis, coral beauty, manadrin fish, a royal dottyback, and now one clown after the otherone died yesterday.
Only ever lose clown fish. Now I have to find another female
The list
1st one jumped out. so I modified the tank to stop that occuring again.
2nd one stopped eating and starved after the first one jumped out.
3rd and 4th got from a shop with a disease (one to relace the first sick one they sold me, and that had the same sickness)
5th got a bubble eye thing, and as soon as she was getting better she just died.
This is within a year so I'm not happy.
As my aim to to have a happy little tank with all animals suriviving together.. I am more sad for the lost soles in the tank.
