I have talked to aquatic collection at length -
According to them -it comes down to the way it is stored and transported -which can increase the risk if not properly done -either one.
Either way -these days I would be much less inclined to buy any used tank over 6 months old-and even then..
I can get a pic and right now so not so removable. Gave a rock full of them to @boun11
Had taken the rock out and scraped off as much as possible but they are back…
Been doing the same and may just accept that mushrooms take over the crevices and spots I can’t get.
If I go starfish i really need to move out some coral, my crabs, and a conch for 7-10 days as this specific starfish will vaporize them all- so a bit hesitant.. but could be interesting...
Shrooms are not worth anything -
Can prob get Yumas onto a rock but can’t get them off whatever they are currently on without killing them or damaging rock appearance
So once again my tank is on the verge of being over run with mushrooms and yumas.
My current plan is to remove the euphillia and either sell them or have some one hold them, or put them in my sump for week or two and cut the starfish loose in the DT for one-two weeks and then rehome it...
I had an aiptasia issue for a bit. First released a bunch of Bergia. Got rid of a lot of them. But I had one big cojone left. Got a filefish -devoured it in 18 hours -yay but then went after my softies (demolished a bunch of zoas in 24 hrs) and was removed.
The big one grew back in 3...
We now have it so that the tank is set up on solar a battery- then a liquid natural gas generator is plugged in automatically if the battery/solar runs out.
If that fails -then the fish tank may be least of the problems…
A point brought up by chat GPT -is that no animal can actually digest silicone (as far as we know) -but if the silicone is compromised (due to kalk among other reasons mentioned) so that various species such as snails and worms can get in and bore through it).
