I went away for 4 days and came back to a bit of a green algae bloom :D. I was unable to find my pom pom crab in any of her usual spots. It's a 10G tank, so I can usually see her. She is now MIA for many weeks and presumed killed in action :(. Can anybody offer ideas why? There is no predator...

I introduced a derasa clam and a cleaner shrimp at the same time about 2 months ago. All my research led me to believe they're compatible. They had been doing fine since. But yesterday I saw the shrimp pulling at the clam's mantle. He tore the edge of one of the clam's openings. I placed a...

Hello all, not sure if this is the best forum for this question. I saw just today that my pom-pom crab is toting a cluster of bright orange eggs! Can I take special care to hatch these, or do they not stand a chance to survive in my tank? Livestock are listed in my signature.

After adding certain rocks from the LFS I began noticing amphipods. They multiplied rather quickly and look like the profile photo below with the black background. There's a larger (9 mm) creature that looks similar to the others, except its antennae are longer (about 6mm) and I can see two...

I just noticed this white blotchiness today behind the fish's right eye, on the orange skin. Can anyone help me out with this? When I got him from the store, one of the other clowns in the tank had a bad case of some parasite around its head. I wonder could it be the same thing? 1. This wild...

I just installed a LED strip for lunar lighting. Here are some shots of the tank and how it lights up some hermatypic inhabitants.

Here are pics of my new derasa clam, named Chowder. I put him in sandy substrate, but I'm concerned that some hermits are digging Chowder up to get at his foot. Anyone else have this problem? How deep into the sand should the clam be buried? Must it always be oriented with the mantle upward...

I am using Instant Ocean reef master test kit to monitor water in a 10G tank. Initially, pH = 7.8 and alk 3.5. After supplementing water with Seachem marine buffer, pH = 8.3, but and alk = 7.0 (which is outside the kit's range) according to test kit! Is this expected or dangerous to livestock?

How do I protect the feather duster from hungry hermits? I've had a feather duster in the tank for a month+ now but have had to keep relocating and reburying it because some mischievous dwarf red hermits keep pulling it up to pick at the soft purple sheath. I've tried burying it 1-2" in sand...

I'm trying to understand what the purpose is for moonlight in a reef aquarium. Is it functional to the livestock, or simply aesthetic? I've heard two perspectives: 1. So-called "moonlight" is a low-power light of a color that is imperceptible by livestock in the tank. The purpose is to allow...

I need to raise my pH from 7.8 and alk from 3.5 mEq/mL in my 10 gal using Seachem Marine Buffer. It was recommended that I should add 1/7 the manufacturer's dosage at 7X frequency to minimize spikes in water condition. Is this necessary in your experience? The recommended dosage is 1nc/day until...

I introduced a 1" nassarius snail to my 10 G tank last week. It's the only sand sifting animal in there. Only once have I seen it surfaced, all other times I only see the tip of his siphon in the sand, which changes location every few days. How do I tell if it's healthy and feeding properly...

This little critter (1mm long) has a forked / dovetail. Saw it on the glass. What is it?

Looks like a conch/whelk shell. Length is 1 cm. Appreciate your experienced eyes!

I read that a good lighting scheme would be 9-11hr period of actinic plus 8 hr daylight within that period. I would need two bulbs on independent timers to achieve this. The kit I received as a gift has a single 15W Coralife 50/50 bulb. can I replicate the necessary lighting with this single...

For reefers, does anybody have a recommendation for a chiller for a 10g? Has anyone ever made a DIY chiller project?

Fellow nano reefers, does anybody have a recommendation for a chiller for a 10g? Has anyone ever made a DIY chiller project?

I got live rock and an empty shell from the LFS today. Dipped it in my water before intro to the tank and found a small sea star stowed away. It's beige, 5 stubby arms, 4mm armspan. It came from the store reef tank. Is it safe to intro this to my 10G reef?

What would you suggest for cooling a 10g reef tank? I'm concerned for this summer because last year we had a week-long heatwave with indoor temperatures around 90F. Fans? Nano chiller? It would be good to have something low maintenance if we had to leave town for several days.

Hello all, I have a 10g reef with 6 red legged hermits. The largest one (2cm shell) roams around and bullies the smaller guys (1cm shell). He'll flip them over and claw at them inside their shells. Of course, he doesn't bother the very passive and larger electric blue in the tank. Is this...

What's your advice on how long to set my light cycle? I am now on week 9 of a new 10G reef setup. According to this helpful article, Aquarium Set-up: Step-by-step Guide to Creating a Reef Aquarium I cycled my tank with 8 hr light. Lots of hairy algae grew. Then I added a CUC as my first...

Over the last week I've noticed a scale or two floating in the tank. Today I just noticed today that my chromis (the only fish) is missing about 5-10% of his scales! Is he sick? Does ICH cause this?

We added a cleaner shrimp to our 10G 2 days ago. He was happily exploring and finding his cleaning station, getting friendly with the tank's chromis ( the only fish). This morning he seemed fine and then in a matter of hours I found his laying on his back on the bottom. Any insights? my...

After 6 weeks of cycling, I added the first livestock to my 10g: 6 hermits, 3 snails, 1 chromis. Two questions about the chromis: 1. In the store, it was schooling in a larger tank with about 20 chromis. Is it best to give it companionship in my tank? 2. The store recommended 1mm pellets but...

I added a crew of 7 hermits and 3 snails to my 10 G tank. Overnight they really cleaned up on the green algea. How will I know if I need to supplement food for them? One chromis is the only fish in there now.
