Something eating my frogspawn

[captan42]

So I had 2 frogspawn in my 30g breeder, for the last 4 months they were both fine, healthy but very little growth. I was out of town earlier this month and came home to find my green frogspawn completely eaten, nothing left but it’s skeletal structure.

I had some weird hitchhiker that was identified here as possibly a nudibranch. Was instructed to pull it which I did. A few days later found a smaller one, pulled that. Haven’t seen any since (but they only come out at night).

This evening I come home and find this to my tan frogspawn.

Whites on.

Nothing is new in the tank other than a Halloween crab and 3 sps frags (they were dipped).

To me it looks like something eating it, I see no brown jelly disease and I haven’t caught anything on them.

Any help? #reefsquad

Thanks

Try a dip in CoralRX and see if any flatworms come off.

So I dipped it last night in bayer, that’s what I have used for my coral dips, didn’t see any worms or critters fall off. Didn’t have coralrx in my inventory. It is on the way now but too little too late.

This morning I came home and this frogspawn is now only a skeletal plug in my tank.

Dumb question but I should toss this right? No way it will come back?

Can flatworms really kill a coral that quickly? What can I do to treat the tank? I have a few sps, 2 shrooms a toadstool and some polyps and a Aussie wall torch. Those appear to be fine for now but I would like to get another frogspawn when it’s safe.

I do know I have some type of worms in my tank, I see them occasionally at night on the back glass. They looked like bristleworms but I am no expert and didn’t get a pic.

I'm sorry you lost that coral. I think it probably wasn't attacked by predator or pest. I've seen Euphyllia frags just die off suddenly like that, without apparent cause, in tanks where everything else is thriving.
