LF nudibranch---I'm overrun with apistasia

[monocus]

i recommend 6 berghia for every 100 gal.acclimatize them in your sump until lights out,put them into a shot glass and sink the glass.let them crawl out on their own.don't disburse them to different areas of your tank.they need to find each other and mate.when they feed they gang up on a single aptasia and devour it,then move on to the next,and it's the baby s that are the real killers.the least i would put in a tank is 3,to make sure they mate and produce offspring
