Gobies...I have lost five of them in the span of 3-4 months

1st: Yellow Watchman (YMG) Died on third day (saw my red shrimp holding it)
2nd: YMG It's burrow that was shared with a pistol shrimp got "raided" by an emerald crab. The YMG went MIA and i considered it gone after a month.
3rd: YMG it jumped through an unlucky opening on my lid overnight. Found it on the floor all dried up the following morning.
4th: diamond goby went MIA after a week in the tank and i considered it gone after a month
5th: Red firefly goby jumped out while i was performing maintenance with the lid off. My attempt of CPR was unsuccessful.

Other than the most common ones, such as ICK, GHA and problems alike. The devil I delt with was a mantis shrimp about 3 inches long that came with the wild live rock I ordered. It killed almost 8 fish in a total of 2 months. It took me a while to figure out I had one, since the rate of dead fish was alarming. Luckily I trapped it and rehomed it.

The all invasive and deceptively beautiful Blue Clove Polyps. They’re gone now back to H. E. Double Hockey Sticks.

Dino

No praying here (atheist), but I think pretty much anything problematic in this hobby is solvable with effort and education. Dealing with dinos was probably the most taxing, at least until I learned how to keep them at bay.

Aiptasia for me because you can never 100% rid your tank of them.

I got a coral on some liverock and in a couple months a singe aptasia popped up super glued him in his hole and have not seen one in 6 months.

I have won against cyano, against dinos, against flatworms, and rogue, suicidal anemones. I have beaten rapid tissue loss in leathers, even aptasia. I thought 'hair algae.... i got this.'

But for the love of everything, Green Hair Algae is a devil I would never curse anyone with. You think you are winning and then it explodes over night. It starts with water changes, manual removal, change in light schedule and nutrient control. You add a skimmer, refugium, change foods, and add phosban to attempt to starve the hair algae. Nothing beats it. The hair algae starts laughing at you. Everyone says to do everything you have already done. You're getting frustrated. You start doing crazy things like hudrogen peroxide, vodka, Vibrant, and other bottle bacteria. You debate on rip cleaning everything and praying you dont kill your fish and the one coral that has survived it all.

Ahem... needless to say, GHA. Not great.

bryopsis and turf algae. both almost had me at my wits end. currently, its metals showing up in my ICP results. has lowered due to polyfilter/new chemi pure blue(should've gotten elite..).

I lost this fight on my 20, I had a very fuzzy algae which would stem off from the rock. Wasn’t sure if it was bryopsis but all of my research pointed to it. Nothing got rid of it for me

i ended up tearing the tank down. Currently have my surviving corals, and my fishes along with CUC in a 10 G holding tank which will be a Coral QT tank on a new 10 G set up.

from now on always going to QT. I’ll never add corals after a purchase, not worth risking any pests and algaes that could be avoided by QT for 76 days
