Its a Peeble Crab. Need a soft substrate habitat where it spend most of the time buried. Nice catch!

That's a Hatpin Urchin, echinox calamari. There are thick long banded spines and shorter, thin fine spines. The thin fine spines are the stingers. Its sting is very painful, like bee sting. Not fatal. If its just a singer stab, the pain should subside in 2 hours. Cheers

Yes, as what Fuel mentioned, the hot water treatment is good. To what extend one could be affected depend largely on whether you develop allergic reaction and the species of urchin. Oftentime, its just the severe pain that subside over time. Should you develop a fever, puffy eyes or increase heart beats, best to consult a doctor. Stay calm though. Do you know what species it is?

If the bioload allows, a naso tang will love the lobo

Dear all, Glad you like it. But the method is neither a tip, idea nor suggestion It's an effective working solution. Been there done that and it works everytime Have fun!

Bro Klim, Don't panic Isopods are very easy and fun to remove. They are great scavengers and absolutely love blood! Here's how: Go market, NTUC, Sheng Siong etc and get hold of some small size kuning or kambong fish. You only need two pcs. A length of string longer than your tank depth and a fish net. Preparation: Scale the fish and wash clean. Cut a 2.5inch section, taking the head to the belly portion. Don't wash anymore. This is your bait This is what you do: Tie the bait to one end of the string. Peel open the gill cover to expose the gill. Give the gill a pinch till a bit of blood trickle out. Lower the bait to the tank bottom and watch The blood trail will start to drift with the flow. Soon, you will see all the isopods 'fly' excitedly out of the substrates and home towards the bait. In no time, the bait will be swamped with voracious isopods eating right into the carcass. Goosebumps! The actions can be so dractic the entire carcass seem to come alive and start 'moving' When a good number are seen devouring the bait, raise the bait with string GENTLY while at the same time, scoop the whole thing up with the fish net. Walla you get a big bunch of isopods for a cool macro shot Tip : Do not wait for every single isopod to land on the bait before pulling the plug 'cos those that have their fill will quickly leave. You can follow up with the next baiting. Have fun

Yup, the variety of favorite fish caught is amazing. Keep wondering the number of time each fish need to undergo the bladder needling before hitting surface... What a painful ascend

Excellent efforts For the simple reason that more are still appearing indicates their huge population you got to deal with. Good move to have the corals in the fuge to provide them with lightings while the lights are turned off. Take note though that some of these pest may be hosting on the coral bases and you need to deal with them too. Yes, you missed out something - treatment duration For mechanical removal, the process need to be repeated daily till they are gone For cutting off lighting, it will take about 10-15 days to starve out the zooxanthelae.. It will be good to mechanically remove them while keeping the lights off. Place filter floss in the return pump compartment to prevent those from the corals finding their way back to the main tank. You may consider getting a bottle of FaunaMarine Ultra Pest Remover to treat the corals before returning them to the main tank. Have fun

I suggested two solutions. Which did you tried?

Good efforts in getting the photo of this tiny fella though its not clear enough for a positive id. If it is Boloceroides, it may be removed mechanically by scraping them off the glass pane and running the water through a filter sock. Repeat a few round to progressively decimate its population. It also resemble hydroids. Hydroids are dependent on the products of zooxanthelae residing within it's tissues, which in turn is dependent on good lightings to thrive. Cutting down or turning off the lightings will kill off the hydroids. Whatever it is, enjoy the process. Cheerful reefing

Calcinus tibicen, blue eyed hermit. There is a variant with dark blue legs but eyes are similar.
