Arrrghhh! Stupid clownfish keep commiting suicide!

All previous posts aside.

I think the reason you are having soo many of the clowns jump is due to the size of the tank and maybe how it is aquascaped.

Regardless of whether you have had success in the past with this size of tank and clowns, and all the others who claim the same, it is a very small area for the fish to react to each other.

Even if the are paired together, the non-aggressive dance they can perform leads them into quick darts and short chases within the area.

Likely one clown is reacting to the other by darting aside, but with no room to dart to, it sadly ends up going up and out of the tank.

If you insist for your tank to work for you, might I suggest the following;

-upon adding another new clown, rearrange your aquascape a little, this may help as neither fish would have a pre-claimed territory, and will likely look to each other for safety.
-if the clowns tend to huddle toward a certain area of the tanks top corner, try suspending small rocks there for them if possible.
-debating on the tank size, often another fish can take the clowns focus away from each other and on the 3rd tankmate, although it should be less aggressive then the clowns themselves and something that is not a purching fish but a swimmer.
-not sure if its possible with your system or concept, but an anemone could help also??
-you are doing the right thing by having one larger then the other, continue this.

Better luck in the future.
