    yes they are known to eat aiptasia and nudibranchs are very specific to what they eat, meaning if you don't have what they eat then they starve and die (some releasing very bad toxins into the water upon death) I think those particular ones do have some predators that we put in our tanks in the butterfly fish and wrasse families so you may want to check your stock against what you have and their known predators

    About 8 months ago I bought 10 of them and put them in the tank. I also have a wrasse in the tank and I was well aware that chances were that he would pick them off one by one. But I was hoping that they would start to breed and multiply. A few months went by while the aiptasia slowly started to disappear but I noticed that it started to slow down until finally I couldn't see any signs of them anymore. So either the wrasse one out or the nudi's all died of natural causes.

    I guess if you didn't have fish that eat them they would tear up the aiptasia but unfortunately that wasn't my outcome.

    Got me 5 of those on an impulse buy when in UK 3 weeks back. Placed them in a cycled 10 G on their own to start a colony as I don't have any Aptasias. in the last 3 weeks I have added around 20-30 aptaisas to the tank and they all disappeared. I have even tried spot feeding the aptasias hoping they'll reproduce before getting eaten but so far with no luck. Can't really rely on getting aptasias from friends anymore as if they could take out more than they already gave me they would be ablet o take their aptasias out. So es they are abolute aptasias eaters. They will starve without those but I doubt they can release anything in the water when they die as many people use them to deal with their aptasia infestation and they starve and die in their tanks afterwards. I can't even find them in a 10 G tank so it's next to impossible to find them in a larger tank.

    I had horrible aptasia in my seahorse tank a couple years ago. I put 2 beghia in the tank an within a couple weeks I had less aptasia and more berghia. I started selling them to local hobbyist (cheaply) until I couldn't get enough aptasia. My tank was 100% aptasia free as well as my friends tank. So yep they work as long as nothing in the tank is eating them. They also need stable water especially salinity. Aclimate them slowly and place them on a rock next to a small aptasia. Better yet put a small aptasia in the bucket while aclimating. The need to eat often so if they don't find food quickly they will die. When eating properly they should be a brown color. White berghia are hungry berghia. Aptasia X Joe's juice all failed me. Breghia was the only thing that cured my out break. Good luck

    How can they start a colony without food? I suspect you cant find them because they all died. I was able to easily find them in my 55g.

    If you read further below you see that I added around 20-30 Aptasias from introducing them till now and all Aptasias are disappearing. Just added around 10 Aptasias 3 days ago and started a small tank with Aptasia to try to get a constant supply of food. the ones I received were very small around 0.5 cm so it is difficult to find them in the rocks. So far I have only seen one once at night munching on an aptasia.

    Oh misunderstood. Good luck I think getting a steady food source is the hardest part. At least I was for me
