good question...

 

[SVXH6]

i think the ones that are extremely aggressive and kill there anemone are in an anemone that is very undersized for them..the more aggressive clowns with there anemone like the GSM naturally host BTA's.. in the wild the would have an extremely large "field" of BTA's to host in,and spread there anemone love around too.. usually in the tank there is one medium sized one to host,which shows the aggressive nature in which they host..give them a few and they would spread the agression(or love) around like mine did!! this is all IMO..

I agree with what SVXH6 said. I have a pair of GSM's, one very large and one smaller. I have 3 GBTA's in my tank. Two are newer, from a recent split and one is older, the remainder of a bad splt from a previous GBTA.

All BTA's are fed on the same schedule, yet the oldest one remains very small.

The GSM's are ruff when "loving" the BTA's. I believe that the older BTA has remained very small to avoid the "love". The other newer BTA's are bigger and can handle the interaction.

Just my observations.

Several reasons- some are not fully known or understood.
Wrong symbiont (anemone/anemonefish combo) is a major factor...
so is the size difference between anemone and fish.
The maturity of the fish is a factor.
Competing species (of fish and/or anemone) in the same aquarium is a factor.
Captivity itself is a factor, but it's not been fully explored.

It helps to understand the relationship between anemone and anemonefish in the ocean: one is not found without the other. In captivity, predators are absent. The anemone isn't aware of this fact, but I think the fish recognize this.
