Noob stocking questions

So I have to steal my wife's thunder and report that we have our first fish. It's really her hobby, but I've become hooked during the tank cycle. We're lucky to have begged, borrowed, or stolen a great deal of equipment. I had a question about where to go from here.

Quick background:

40g breeder that we're starting with fish only, but sounds like either this will morph into a reef tank (or once we keep fish alive for a while, we upgrade and go bigger at which point we try coral).
1.5-2" of sand (was live when bought, we dumped in maybe 3 double handfuls and washed the rest)
60 lbs live rock that came directly from a tank breakdown. Also got ~8 hermit crabs of various sizes, 3 nass. snails with the rock and was lent a couple types of polyp & tube corals to see if they blew up. Everything lived fine while the ammonia spiked and is still with us after getting the fish.

Had ammonia spike, then waited for 3 days of zero ammonia before adding a firefish. He found a cave in the back of the tank and is eating well so far. Still monitoring ammonia and I understand that future stocking plans will really be dictated by the chemistry and how the fish, crabs, snails are doing but wanted some recommendations for our future purchases.

First question: should we be patient or rush in and use the rule of thumb of "whatever fits in the tank with gentle pressure?"

Kidding...just letting everyone know that we're aware of the need to take things slowly.

Actually a quick background on our fish plans and accessories before questions:

Definite:
2 ocellaris clownfish
blood/fire shrimp

Possible:
pearly jawfish
still researching other fish

If it's important to know, we have the following hooked up:

Coralife dual linear T5 strip, 18W 10k and 18W actinic
Koralia 3 and Koralia 2 for flow
filter for up to 60g tank, says 3 stage (i think it's got scotchbrite-type pouch full of charcoal and then looser scotchbrite, called bio-pad or something...it's supposed to house our nitrifying bacteria which I hope is really in the sand and rock)
Remora? skimmer driven by Rio 1700?
200W heaterstat

OK so now the questions:

How will the shrimp affect the bio-load? Does it count as a fish, count as a fish but perform cleaning to offset, or not count as a fish and purely part of the cleaning crew? Is it possible/advisable/insane to try to add this as our second livestock?
For the jawfish, we don't have much sand at the bottom. We're hesitant to pour another 2" or 3" of sand into the whole tank just for a jawfish or two to make burrows, is it possible to make a hill or two, possibly around a little pvc structuring to make some vertical homes for jawfish?
I'm intrigued by a fluidized media filter for biological filtration, but don't know enough about the oxygen requirements of the different types of nitrifying bacteria...I will do more research but if someone has recommendations on these things it might be helpful.

Many more questions but at this point I'm just trying to figure out if a shrimp is appropriate for our second inhabitant.

Thanks in advance,

Well you def didn't cheap out on any details :p

Had ammonia spike, then waited for 3 days of zero ammonia before adding a firefish.

Did you have the nitrite and nitrate spike and fall as well? With LR from an established tank I'd still say you're fine for now as the cycle was prob very limited

Looks like a great stock list...

How will the shrimp affect the bio-load? Does it count as a fish, count as a fish but perform cleaning to offset, or not count as a fish and purely part of the cleaning crew? Is it possible/advisable/insane to try to add this as our second livestock?

I'd say yes and no... It won't add nearly as much waste as a fish but the impact should be minimal... I'd give the tank a week and test ammonia, nitrite and nitrate and if they're all in range try the shrimp...

For the jawfish, we don't have much sand at the bottom. We're hesitant to pour another 2" or 3" of sand into the whole tank just for a jawfish or two to make burrows, is it possible to make a hill or two, possibly around a little pvc structuring to make some vertical homes for jawfish?

You could add sand more sand and make the hump on one side but knowing how PITA fish can get it would prob still make a home in the shallow spot :p

And are you concerned that adding all that sand will mess up the tanks parameters or just that you won't like the look of it? If it's because of messing up the tanks parameters you can add it slowly over the coarse of a few weeks and it should be fine...

And on a final note glad to hear you're taking it nice and slow and asking questions... It'll be worth it in the long run!!!
 
Resurrecting thread since we're now at the next stage and may need more advice.

I understand about the sand, we may think of adding more over time. If we get the jawfish, I'll likely just pile up some sand around a PVC house I made for him (I have a house for him but no fish yet).

I took all the advice and waited, then added shrimp. He did fine for a week, all testable parameters (ammonia, nitrite, nitrate, pH, SG, temp) didn't budge. Then added our 2 black ocellaris, they've been in a week and are doing great, eating, wobbling around :). Again no real budge in parameters. Yesterday I put in another 25# LR from an established tank that was out of water for less than a day. I did a quick scrub w/saltwater before adding, and got pretty murky water. Didn't smell rotting, just a little seashore-ey. There was a minor ammonia reading after adding it (less than the first "positive" bar but certainly a different color than the 0 I had been getting). 15% water change and no ammonia detected.

Anyhow we're now at:
firefish
2 clowns
1 cleaner shrimp
bunch of crabs/snails

We're thinking 2 more fish, and were initially thinking of a 6-line wrasse and a scotter blenny. However I've heard from a couple independent sources that they may compete for food. So I'm looking for a confirmation on that, and if so some recommendations for a fifth fish if we get one or the other (6-line or scooter). Another option is the pearly jawfish and 6-line, not sure if that's any better. We kind of want at least 1 more fish that's likely to swim around in the open some, which we thought the wrasse would be good for. For instance, the scooter is interesting because he scoots, but he kind of sticks to surfaces if I remember. And the jawfish is interesting but I get the sense that he's going to just camp in a hole and not be out much. Our firefish loved being front and center but now that the clowns are in he pretty much sticks to the back in a little cave.

I'm sure this is all unclear, so basically the question is: is there a fish that is likely to swim around in the open (be visible) that we can have with our current stock list plus one of the following?
scooter blenny
pearly jawfish


Another related question is: is one or the other of the blenny or jawfish (or either) a bad idea with a 6-line wrasse?

Thanks in advance,

Both the blenny and the wrasse will prefer to eat only live pods in your tank so a 40 gallon is a little small unless you intend on setting up a sump/fug to grow pods in. I used to have a problem with too many pods in my 58 until I got my 6 line. I haven't seen one in months now.
Switching to a herbavore blenny like a lawnmower or a starry blenny might work. Both are very cute with lots of personality.

One quick word of caution..my 6 line was cranky one day and terrorized my firefish right out of the tank. He also used to tear up my maroon clown pretty bad. Add it last if you do get one.

Good luck :)
 
I hope you plan on having the top of that 40 breeder covered at all times if you get the jawfish. They are infamous jumpers, and the tank is shallow.
 
if you added more LR yesterday, then I would wait another week. you may still get an ammonia spike from the new rock and it may take a few days or more from the decay.
Just my opinion.
 
Thanks for the thoughts. We have a brand new quarantine tank as we're getting to the point where a crash would make me really mad. So anything we get will be in qt for prob 3-4 weeks anyhow.

The tank is covered, thanks for the tip.

And thanks for the tip about adding the wrasse last if we choose to go that route.

I think it's a jawfish for now. If he ejects, it will be sad, but it will leave another fish slot open :rolleyes:

Another 40 breeder reefer! Welcome! I also had bad experience with the six line wrasse..he was beating up my maroon pretty badly and I had to tear apart my tank to get him out of there.

Be sure to post pics soon! You should start a "tank progress" thread like mine (see sig). It really is cool to look back and see how much the tank changes over the months/years.
 
Oh btw I have some noob corals (xenia, gsp...) I can give to you for free if you would like to try them out in your tank. Not sure where your located...lmk if interested.
 
Remember add one fish at a time after a spread time of a week each so your ammonia wont spike up and can kill the fish from shock. Your tank can hold more then 2 clowns and shrimp. You can get like 3 clowns , 2 firefish, 1 , royal gramma , 1 blenny. You might be able to get a tang in there (Yellow Tang) after a while. But dont jampack your fish stock. You can get away with 8 3 inch fish in there.
