Some Mandarins will eat live Brine shrimp and that will sometimes but rarely get them to take frozen food like Cyclops, Brine or Mysis.

Their primary diets consists of copepods that live in and on the live rock and sandbed.
Did the person at the store ask you the size tank you have, how much rock, if you had a refugium and how long the tank has been set up?

Any Dragonette like a Mandarin or Scooter really needs a tank with at least 100-200lbs of live rock and a refugium as well and be established for 9-12 months before attempting to keep a fish like this that 99% of the time will never eat anything other than copepods.

They need to eat a ton of them too. They eat constantly while they are awake and at a rate of about 1 pod every 3-5 seconds. Doing the math, a Mandarin can eat upwards of 12,000 pods per day if they are awake for 16hours and only eat one pod per 5 seconds.

Most people should never buy these fish unless they research their feeding needs and then set up a system that will sustain them.

Mandarins have one of the highest mortality rates of all the fish kept in the salt water aquarium trade.

I'm sorry but you should really consider returning him.

The spots on the sand sound like Cyanobacteria which happens usually due to lack of water flow.

Clean up crew will help but mor flow should be added as well.

In a 30g, try about 5 turbo snails, 3-5 Nassarius snails, 5-7 astrea snails.

Maybe even a small sand sifting Goby like a Hectors or Rainfords.

A good protein skimmer does pretty good job too. If you don't have a cleaner crew a good skimmer is a must.
Agreed with Schigara, more flow- less algae, thumbrule.
Dragonettes won't survive in an unestablished system, other tumbrule.
Conchsnails also does great job on sandbads, but they also attack smaller snails and crabs..you don't want that, but they stir the sand like crazy.

On the other side.. I'm not sure that you're dealing with cyanobacs or nuisance algaes...Where those red and green spots are? On the surface of the sand, or below?

Dick,

Totally agree with the skimmer. I would never run any salt without one. Once you see the organic crap that comes out, you'd never want to go skimmerless again.

all the main issues have been covered by the pro's ....lol ....now for the snowboss's low tech tip of the evening............
.get yourself a good old fashion turkey baster {note: not your mothers/girlfriends/wife/other} they won't be very happy, lol} and just gently "blow" the crap off the sand and rocks everycouple of days and let the filter and skimmer take care of it...........i did it daily for a good month straight and until i got some algae hermits a few weeks ago i was still doing it every week to ten days or so ...................................
