Its a cube, but again… no power tools for me. So I need a virtually no tools solution. Either that or pray that the fish are not jumpers 
The two candidates for jumping are a chalk bass and some type of smaller wrasse.
You can pick up a sheet of egg crate from lowes. It is a techincally a light diffuser, but allows most of thelight through to the tank. It’s just a series of plastic squares. Allows heat to escape and light to enter. I think most people in the hobby use it if they’re going to use anything at all.
If you give me the dimensions of the tank I can check my scrap pile when i get home to see if I have a piece that fits. If it’s from the scrap pile you can have it.
Are you sure its glass? Most of the smaller nano tanks are acrylic???
Well the website says it is a glass aquarium so I’m going to go with that.
Cdangel0 if you have a piece that is this size: 19.75"x 17" then that is what I would need. yes I have been debating about buying egg crate because I wanted something to hold my filter floss up the filter. I was supposed to get a measured out fitting back there that has worked for other aquapod owners but the guy never sent it… oooops oh well
OK. I’ll check my scrap corner when I get home and let you know.
I just checked, unfortunately nothing quite large enough.
Sorry.
Just keep in mind that the eggcrate is going to block/reflect quite a bit of your light. Also, smaller jumpers like your chalk bass will still jump right through eggcrate. I had a firefish that managed to carpet surf even with eggcrate. Its just one of the chances you take with jumpers.
Right… well I don’t really know what else to do with them when the time comes. I will try to craft something I guess.
Numbers(params) are still solid. 
Ok params are great… I figured out how to get off the green corraline algae. LOTS AND LOTS of scrubbing/circling with the mag float. If it is fresh then it comes off pretty well. If it isn’t… well not so easily.
Doing a water change tomorrow since it has been a little over a week from putting in the new rock and nothing happened. Went to DPA and couldn’t resist this mushroom. Enjoy!
A new polyp has just opened up on this bunch
The mystery polyp, loud and proud to be different!
One of the green mushrooms has officially split, the 2nd mouth showed up the other day and it looks like another is starting to split and another may also start spliting.
Just a question about the blue mushrooms, how do you measure when it is ok to start acclimating them more to the stronger light? Like if I want to move them higher up some where how long should I let them get used to this light on the bottom and how high should they work themselves up on the rock? Thanks
I personally would give them a week or so where they are… they look pretty happy. After that I would move them up in the tank a little bit and see how it goes. They should be pretty tolerant of different lighting, but better safe than sorry.
Had a little bit of a scare tonight. While staring off into space by my tank I heard an audible “pop” of course I was thinking… you gotta be kiddin me. So I set off on a man hunt to see if I could find a mantis shrimp. Well I saw this little white thing on my rock no bigger than a cm and ends up it is a little crab! Kind of resembles a emerald but it is white! My bet was he was trying to beat up the snail that was in front of him because before I found him I heard another pop. The snail is 2x bigger than the crab though, so he didn’t win, plus I was shining an LED flashlight in there to see what he was I spoiled his meal lol or his prospect.
Also I have what seems to be tons of bristle worms. I saw 7 out in the open during this encounter. I know they are not bad unless they are “big” but was is “big”? Also should I attempt to get rid of a few? Because I seem to have a lot in there.
I would say anything over a foot would be bad. Most of your common bristleworms (the pink and purple ones) are harmless and quite benefical for cleaning up excess food. A bit creepy but not bad at all.
See if you can get a pic of the crab. As far as the popping sound goes, it could have been the heater. I have been scared by that a few times. It could also be a pistol shirmp. Neat little buggers that are more or less harmless. And of course if it does turn out to be a mantis then you could always give him away I know some people (myself included) adore the little buggers and would gladly take one. I’ve never seen the crab you described in my tank or our 90. The only hitchiker that was even close was a small squat lobster that came in on our rock from Dr. Macs. Anyways see if you can get a pic… there are some pretty good people at invert ID in the invert forum of RC. HTH.
I don’t think it is the heater because the pop sounds like it is coming directly from the rock that the crab lives in. Do they keep to the same rock all the time? He is sticking to his rock but he knows how to hide so I can’t get a picture of him tonight or anything, but then again… we shall see what tomorrow brings lol.
I would bet that a glass lid would probably block more light then your other options. If you decide to go with egg create I would highly highly suggest black egg create as you’re trim is black and white will just stand out as UGLY. I think Egg crate maybe be the easiest tool free way to do something. Any sort of netting your going to need to build some sort of frame the shape of your aquarium to hold it together when you want to work in your aquarium or you will be taping it, clipping it, or tying it somehow.
Pops aren’t often crabs or mantis, but possible. If it was a fairly loud pop that you could hear from the next room with the TV on it could have been a pistol shrimp. If the pop was not that loud it could have been a mantis trying to crack open a shell. (typed this before I saw icy’s response)
If the crab isn’t fussy and does in fact look very similar to a emerald crab that would mean it is in the Mithrax genus most likely and may not give you any problems. Odds are though that upon close inspection the white crab will have a good bit of what looks like hairs. If this is the case then it is not reef safe and may need to be removed.
Many people have lots of bristle worms and only see them at night. I don’t think you need to remove any as they are probably only going to help you. It wouldn’t be a disaster if you decided to remove them.
If you really want to get a better look then turn the lights off in that room at night wait about 2-3 hours of total darkness. Get a red LED flash light. Sneak into the room, get a little food in the water to entice things to come out to eat and just watch for 10-15 minutes. Don’t put too much food in though. You want them to smell something in the water to come out of there hiding holes, but all they may need to be happy is a tiny piece.
Good luck,
Jon

If you want to see what kind of critters are in your tank you can always make a trap. Thats how I found out that Keleigh had a pistol shrimp in her original tank. We would hear him popping all the time but never saw him untill we set the trap, and even then it took a while.
Hmmm I might have to try the red LED light plus food. It isn’t really loud, it is only audible when you are in the same room and close up to the tank. The pop isn’t always the same level of noise either which kind of enforces the critter theory although I don’t know how the heater would sound. After a close look at his back, it has slight dark markings (kind of like a pom pom but I didn’t get a very good look at him). I will search tonight to see if maybe there are more colors. He might have just shed or something.
Funny you say he is similar to a Pom Pom. I had a QT tank that I filled with corals when I got back from studying the reefs in the Caribbean this Feb. Since I was busy with school I left things in QT longer then I normal would and two months after the start of QT I found the exoskeleton of a crab in the tank. I very carefully looked in ever rock as I removed the corals to place into another system and just couldn’t find the crab. A couple of weeks ago I finally got the courage to frag up a brain coral that I had let sit in the tank to make sure it was fully adjusted to captivity. The crab was in the center of the rock.
I’m going to try to get pics of mine to get Dr. Shimek and his team to identify them. If you can get clear pics we can as him about your’s as well.
