You want to use this, not just regular glue. Dollar store super glue works great.

Thanks so much - and as it has cyano in the name it must be linked somehow to reefsYou want to use this, not just regular glue. Dollar store super glue works great.![]()

I definitely second the RO/DI advice. I know people have had experience using tap water, but it seems like you run a much higher risk of introducing contaminants into the tank. This may be one of the reasons your star fish died, they seem to prefer a more stable tank environment.This week is seems much better - not much on the sand, and less on the rock. I probably won’t beat it until I stop using tap, though.

.I'm sorry for your loss, it can be pretty devastating when things go wrong, no matter how small the system. We lost our fist clowns and all our coral too. It sounds like you have some good support though, so you'll figure it out!Thanks for the reply! I had a bit of a traumatic night actually. As I was turning out the lights to go to bed, I noticed my smaller clown was clearly dying. Eyes strange, colour off, lying on back. I had NO idea what was going on. Did a water change the day before, changed the phosphate removal as per the advice of the LFS staff, and fed them something new which was supposed to be good for them.
My larger clown was also discoloured and breathing heavily.
At any rate, little clownfish died. Larger one looked slightly better this morning, but didn’t eat. Royal gramma stayed in rocks and didn’t come out to eat (not normal) - yellow wrasse did come out and eat.
I posted an emergency thread on here last night - and it could be that the phosphate removal did this to them! I had no idea and feel terrible. I posted my results - amonia was good, nitrates good (although I interpreted as bad), and phosphate was 0, which is not good - I was removing it to combat the cyano, but to the detriment of the fish without knowing (i assume). Fish were all happy in the tank a few hours earlier.
I shall see what happens when I go home after work.
Ps: I do have a protein skimmer - not a fancy one, bit it works.
At any rate, I can’t believe this happened. So sad.

How long has it been since you last added something "wet" to the tank? The small white spots, and gramma hiding in the rocks, and loss of color / struggling on the sand all sound/look like marine velvet...I see what you mean - however i can’t see them ‘in real life’ - and the one that died didn’t have spots - he did have loose skin tho so I thought brooklynella - but it was too sudden....I think?[/QUOTE
Are those tiny white spots on the clown in the last picture? Could be a parasite...

If he had the sloughing skin that pretty exclusive to brook. And yes, they can hitch a ride on inverts. Inverts can’t be infected though.Brooklynella can kill pretty quicklyIf he had the sloughing skin that pretty exclusive to brook. And yes, they can hitch a ride on inverts.

I want one! I had never heard of that type of crab before, but just googled it. If it will eat from my hands that would be a new one for me!
Noooo!!!! Originally that’s what I thought - but then I didn’t. So it’s possible for a clown to seem really sick but then bounce back from brook? My other clown seems so much better. Sorry for all the questions!
I have never quarantined - I never add the LFS water, but as it’s just a biocube, I haven’t bought all the bells and whistles. Lesson learned I guessWell... parasites have a lifecycle. Brook has a pretty short one. They feed off the fish, and then drop down to the substrate to reproduce then come back, in larger numbers. Fish can build a temporary “immunity” if they are very healthy (wrasses are good at this) but clowns are VERY susceptible to brook...
Treatment would be either acriflavine bath or formalin bath, followed by transfer to a QT for follow-up with 14 days of metroplex (dosed every 48 hours) And your tank will need to be fishless (fallow) for at least 6-weeks.
Best practice is to QT all new invert additions in a fishless tank for at least 6 weeks, up to 76 days (for ich). But, at the very least rinsing your CUC really well with fresh saltwater (or tank water once it’s pest-free again) dramatically decreases the risk of hitch-hikers. Never put LFS water into your tank if you can help it...
