So my partner and I bought a coral beauty yesterday and housed it in our 250l Red Sea - it seems to be showing aggression towards our phantom blenny and potentially nipping at our bubbletip anemones (hard to tell if he’s going for the rocks or the nem) we’ve kept the lights off to see if he’ll settle as he is very new to the tank but if not we have a 200l with a young bird wrasse (4”) and a six line with no potential coral to nip at; would this be compatible for CB? Bird wrasse has a great temperament and has never shown any signs of aggression; I’m more worried CB will bully. (We are upgrading bird wrasse tank this is just temporary)

Other option is a 450l but it houses a jewel blenny, bicolour, engineer goby, pink spot, white watchman, coral goby, regal tang, sailfin tang, filefish, a breeding clown pair, x4 chromis, a large boxer shrimp and a large decorator crab as well as lots of soft coral. (zoas, palythoa, kenya’s, mushrooms, bubbletip nem, pulsing Xenia) Could this be a compatible tank if he turns out not to be a coral nipper? It’s generally very docile minus the female clown.

If all else fails we have another 250l we can set up for CB but I’d love to have him in one of our existing tanks, any advice?

Hey everyone! First time urchin owner and poster :)

So I have a mixed reef tank, approximately 225 gallons currently home to 2 halloween urchins, 2 tuxedos, some brittle stars, sand sifter stars, 7 green chromis’, and a latge variety of different snails and hermits.

My concern is regarding one of my urchins. I have noticed what looks to be the orange spines floating throughout the tank and I believe they’re coming from my one urchin. It moves well and regularly throughout the whole tank on all terrain (rocks, glass, wave makers, etc) but he doesn’t look as “full” as my other halloween in terms of spines and colouring.

All of my other critters are doing wonderfully, I check the salinity of my tank twice a day, I check my ammonia and nitrate levels at minimum one-two times a week, if not more and have no concerns.

Should I be concerned about its health and wellbeing? He’s active, none of my other critters are showing any signs of distress or discomfort, all my parameters are in check, my biggest concern is his lack of long orange spines and that he doesn’t really wear “hats” like he used to.

Thanks so much for any help, I really appreciate it! 🐠🦀

I live in Asia where the weather is hot and my mixed-reef tank is currently placed in a non-airconditioned room. Without a cooling fan, the water in my 55L tank can go up to 30-31 degrees celsius (86-87.8F). I have since added a cooling fan which brought down the temp to a stable 28 degree celsius (82.4F) but the evaporation is quite significant (1L/day) and worrisome when I am out for travelling for a week+.

Should I get:

Automatic top off system to counteract the evaporation

or

Aquarium chiller to further bring down the temp to 26 degrees celsius (78.8F) and remove the downsides of cooling with a fan.

Is it worth to chase the 26 degrees celsius (78.8F)? I've read that 26 is quite a sweet spot for corals to thrive as compared to 28 degrees celsius (82.4F) Perhaps anyone who has been reefing and found success with their corals in 28 degrees celsius (82.4F) could share their experience.

Thanks in advance!

Hi!

We were gifted a tank that was going down hill pretty fast. I’ve had a hello reef without much difficulty so some basic knowledge.

We took the water to get tested and everything was good except the salinity was pretty high. What recommendations do you have to try and save the remaining fish?
