I use a 20g long for my 90g without any issues. It all depends on what you want in your sump I guess.

Hey Michael,

My roommate and I actually just moved from a 75g to a 90g last weekend. I have a 48g rubbermaid tub that was used to hold our fish and some live rock during the move. You are welcome to use it. It's just holding some miscellaneous aquarium stuff at the moment. I live over in the Arboretum area. Just throw me a PM on here if you're interested.

I have a black and white and a true perc that seem to be hosting together in my frogspawn. Hopefully they start to spawn together too

Not the first hotel like this, but cool nonetheless...

Emerald Crabs are a great and reef-safe way to keep it in check. We had a bunch on our rocks when we finished cycling, put in 2 crabs and they had it cleared up in about a week. If you go with Emeralds though...look for ones on the smaller side. Fairly certain "Big Bertha" ate one of our chromis once the bubble algae was gone

As I remember, it was fairly difficult to raise the temp on a significant amount of water - even 100 gallons or so. Adding a few gallons (10 or 15) of water at 15 or 20 degrees lower than the original temperature would hardly affect it all. Am I remembering this correctly? It has been 4 decades plus since HS Physics.

Ya, water has a fairly unique property in that it takes quite a bit of energy to raise or lower its temperature, hence cold lake water in April, warm lake water in November.

I have a question for you. When I was taking physics in high school, my teacher had a standard problem: you have a vat of water at 65 degrees, and into that vat you add an iron ball of some weight and temperature, a block of ice at some weight and temperature, as well as other othings and I calculated the resultant temperature of the water. Do you know the type of problem I am talking about and how to solve it?

Yes I do! My students are working on the exact same types of problems at the moment.

OOOOHHHH...physics. One of my favorite classes due to the teacher. (and you got to smash stuff...how cool is that?)

We are pretty much done with smashing stuff, until the egg drop competition in spring. Now we are lighting things on fire!!

Teacher here

6th grade science, 10th grade chemistry, and 11th grade physics.

do u think that my tank can support one after I finish my 10gallon refugium for the 20gal, I have 25-30lbs of live rock in the main tank and I am going to put atleast 10 more in the fuge along with some chaeto to help grow pods because thats the only reason I am setting up the fuge

I don't think it's necessarily fair to say "you can't have a mandarin unless you have X lbs of rock" because we don't know how you are going to care for said mandarin. In order for your rock to grow and sustain the necessary pods for feeding, no 40lbs wouldn't be enough. From what I've read and heard, it takes about 100-125 lbs minimum of rock in order to grow and sustain a population of pods for your mandarin to eat. If you plan to keep a mandarin in a 20gal, and it won't eat flake/frozen food, you may have to supplement your tank with live pods you can buy from a LFS. This method would get expensive, but have read many articles of people who find the mandarin worth the $20-40 a month they spend supplementing their pod population.

I don't think my true perc. has left our frogspawn since putting him in the tank. The black and white clown I have though hosts in the frogspawn as well, but is much more exploratory.

Was great meeting you Sarah!

I have the Acans under 15000K lights atm, so they didn't darken up, but they still look awesome. They took about a day or so to puff up and get used to the new tank. Also, thanks for the rock, I haven't started to cook it yet (busy weekend), but will probably get to it when I get out of work today.

pm sent on green/white stripe acan

Eh, I have a ton in my tank, and they don't bother anything. There aren't enough on the rocks to hurt the coraline there, and I just see them cleaning off the back wall most of the time.

Curious how this guy works out for you. These critters look awesome, but I've only ever heard about them living a matter of 1-2 months in even the best of tanks.

I like the idea of terra cotta, will have to try that.

I think a mandarin depends more on the amount of liverock you have, rather than the size of your tank. I've seen mandarins kept in a 75g do just fine. The guy keeping it had 125lbs of live rock in there, and the mandarin was in the tank for 1 year, happy, plump, healthy, and didn't eat frozen.

Nassarius may eat a few copepods here and there, but nothing that would affect the overall population of the tank. In my experience, they are more on the omnivore side rather than carnivore and stick to eating leftover food / detritus in my tank.

Bumblebees on the other hand...I try to avoid, as I've read they are very carnivorous and if they can't find the fauna to eat in the sand bed, they go hunting on your rocks for pods.

We're expecting our first child May 15. It'll be a boy, the 8th straight boy across 4 generations in our family.

Hazaa Y-Chromosome!!

All plants produce oxygen gas, but it, more often than not, dissolves into the water. It isn't released in large enough quantities at a time to actually "bubble" out of the plant.

Most likely it's a diatom bloom. Nothing major to worry about as most tanks will have them. This is especially true if you are just starting out and your tank is still cycling.

How old is the tank?

My ceriths like to crawl over my glass but rarely venture out of the waterline. My Astrae, on the other hand, venture all the way to the top of my tank and like to hang upside down on the top. It's a little precarious, considering they can't right themselves up if they happen to fall off...

Hermits have a new home. Thank you Eleyan, nice meeting you.

I could be mistaken, but I didn't think bumblebees ate algae. They are more carnivorous than omnivorous and eat the critters living in your substrate.

I will take some
