I need suggestions, please.
 

Best clean up crew for my 3 gallon nano?

Best fish for my 3 gallon nano?

I was thinking one turbo snail, two of the tiniest hermet crabs I can find, an emrald crab and a peppermint shrimp??

As for fish I was thinking a green chromis, cheap and pretty and they stay small.

I have deep sand so was thinking a small jaw fish or some other sand loving fish?? Any thought or suggestions are greatly appreciated!

Some details on tank :
3.3 gallon
2" of sand,ten pounds I know it's way to much...
3 pounds of live rock rubble
Water depth 8" to 9"
Live rock has tons of Hitchhikers, mushrooms,coco worms, different algae ect. All doing well
I use a hang on back filter meant for a 10 to 15 gallon tank,it has a replaceable cartridge filter and a bio filter that looks like a mass of black worms..
Tank temp is 80 f

I would probably do one hermit (but something nice like a Halloween), one snail, and the peppermint. I wouldn't see much of a point with the emerald.

If you want a crab, I would suggest maybe a porcelain crab. They are far more lively, and their diet is more filter feeder style. Emeralds would probably die off quickly in a small tank like that.

As for the chromis, they definitely are not a nano fish. They prefer to be in groups, and are also very active swimmers. I would stick to a small clownfish or a clown goby.

Jawfish are not nano fish either. They probably need at least 20-30 gallons.

With the deep sand bed, You could get away with a pistol shrimp and goby pair.

In a tank this small.. I would stick to one fish max.

Cool! Thanks fishyfishy, I'll do some reading on porcelain crabs !! They look really neat :)

yes I was going to suggest a Halloween hermit as well. They are the best cleaners out there for algae on rocks IMO. I would also stay clear of the chromis , maybe look at some of the smaller blennys they have great personality . Had a few griesenger gobies a while back when I had a nano a little bit harder to find but one of the coolest fish out there. Or you could look for a panda gobie also not as common but would be perfect for a nano .

Awesome!! Thank you!! This is great please keep the suggestions coming.

I think I'm falling in love with gobies !!

Trio of Trimma gobies!

A deep sandbed can cause issues, so be aware of what you're getting into

I haven't retained all I read about them, so you'll have to look on the web

All I remember is I stay away from them

You could do a shrimp goby pair like the candy cane shrimp they are like an 1" long and one of the small goby's randals I think only get 2" I can't remember but there are some small ones my bro has a 5 gallon with them awesome little guys mess up the sand a lot but cool to look at

I'm definitely going with a shrimp gobie combo! As for deep sand,I know I messed that up. That's why I'm looking for sand dwelling criters and fish... I heard of snails that burrow in the sand as well??

Hello world!!

Nice! They are fantastic grazers and they look awesome. Good pick.

Already bonded and not even in the tank yet.

Small update nano is going strong.halloween hermit,pistol shrimp and goby all still alive and well lol. Been doing 10-20% water changes every 7 days :) things seem to be happy!! :mrgreen:

Halloween hermit crab moulted :)

When using hang on back filter how often do you change the replaceable filter? the one with carbon stuff in it? I know not to touch the bio filter.

The carbon has a very limited effective lifespan. After a week it does very little but still works to some degree for another couple of weeks. I would personally change the filter every 3-4 weeks but rinse it out with each water change. If I understand you correctly you are using the type of filter pad that has the carbon and filter pad as a single disposable unit. If you have one with a sponge and carbon separate then just replace the carbon and rinse out the sponge as the sponge will last a very long time.

Thank you!! :)

spike-fin goby is the best goby for a "stablished" nano IMO

Look into clown gobies and neon gobies too.
Small tanks get tons of algae so might want to get an spiny star Astraea to clean the glass.
If u have good lights than a rock flower Anenome may do well too.
