Cool! I couldn't find much info about the Berghias, other then one per 10 gallons. I've got about 30 aiptasias in my 350 display so yeah.....not liking the cost of that! I have an cluster of about 10 aiptasias that I can at least release them close to a big food source.
So you are 2 months down the road?
Do you think they so far have just stopped the multiplication or have actually dented the population 20-50%?
Have you found any Berghias in your sump? I have visions of that I buy a bunch of Berghias and then they just multiply in the sump to repopulate the display a year later.
So this is the same rock on the right side of the tank (circled in red on FTS). I released all the berghia on the right side base rock, wrasse sleeps on the left and wasn't sure if he was gonna try to snack on them. (He ignores them so far) there are still like 2 or 3 large aiptasia on the rock where I released them, to the right of the purple line, but that's all that's really left (on that side of the line)
Left side of the tank is still infested, I still have them popping up over there, even in the sandbed, though I have seen one berghia over there on the hunt.
Overall, I think the number is less probably, I just think the Berghias need to get to a population were they can eat the aiptasia faster than the aips can reproduce. That's probably why they recommend so many of them to start. What I have read says they are pack hunters, but I've only seen them attack individually. That's probably why the big aips are still there..
I have not found any in the sump.. I am running a filter sock and some cheato down there, so I dunno if I am filtering them out/removing with cheato, or if they are not making their way down there.
They are definitely making progress in the biocube as well, 50% reduction of aiptasia in there, they got a couple that had sprouted under the GSP on the sand bed.
The aips were stinging the GSP and that portion is already recovered and it's starting to grow again. I think the smaller tank gives the berghia an advantage.
I have debated pulling a certain infested rock (thats not attached to strongly) and putting it in a 5g bucket with flow and heat, annoying the aips to cause them to reproduce and maybe catch a few in the tank and have a backup culture... if i do that you are welcome to have some. Otherwise, once I'm clear in the display if I can catch them, I can pass those along..
The other day I saw you had the 350g on the local forum, thought you had sold it? Guess not?! Lol
