View Full Version : Shrimp in Brackish tank?

Since we can't have the normal catfish or clean-up crews that we can have in a FW tank...what would you suggest for a BW tank?

I went to Terry's AquaLand (Terry is the owner and the only one I will talk to about fish there) and he said that some hybrid "mutt" feeder shrimp could clean up the BW tank as long as I was just now starting to cycle to BW. That they will "adapt" to the water conditions and that they are tough to kill.

Honestly, they look like ghost shrimp with a few red spots over their tails and bodies and small bright red claws on them--different then I see on the internet pictures for ghost shrimp. They are only 1/2 inch to an inch long. Could it be a hybrid or FW/BW shrimp? Or a BW shrimp that is being sold as food and they just don't care? I tried to take a picture of one but it doesn't even show up in the tank!

I did buy 6 of them and put them in the tank with the gobies hoping that the little guys might just make a meal of them if nothing else...but they are all still in there this morning (bought them Friday afternoon)...drats!

Any suggestions on what "mutt" shrimp this could be and the possible problems I might have with them in the BW??

Well, ordinary ghost shrimp live well in brackish water anyways. The ones that don't get eaten by my puffers have lived in my tank for several weeks now at an SG of 1.005.

I wouldn't trust his "mutt" shrimp and I'd just buy some ghost shrimp, quaratine them for a while, and use them as your cleaner crew.

Ghost shrimp come as both FW and BW species, which are extremely difficult to tell apart. The BW species will live indefinitely in BW, the FW ones for some weeks to months. And the reverse, of course.

Is that so??? I guess I've got a lucky batch then.

I suspect those are simply regular Palaemonetes paludosus, acclimatizable (if rather unsatisfactorily) to brackish salinity.

Hum...then I will watch those guys closely. So far, they seem to be doing a crack-up job of cleaning and are very active! The SG is just below 1.0 right now, so I still have a few weeks to go for the full BW effect.

One of the shrimp is carrying eggs and it looks like ghost shrimp eggs to me (from pictures on the internet). Unfortunately, I have to say that if the eggs hatch then the gobies will have a meal...these 6 shrimp where only $0.99 and my original thought was if the gobies eat them then "good"...if they live to clean the tank "even better".

I know, not a very nice thought either way...

How can it be below 1.000???? 1.000 is pure freshwater, I thought. Are you reading it correctly and did you calibrate the refractometer??? Hydrometers won't work so well.

Also, even if the shrimp did hatch, your chances of raising the young are slim to none.

When I collect Sailfin Mollies in brackish water, I'll catch ghost shrimp and other shrimp varities right along with them. It wouldn't surprise me if they could handle brackish water full-time. For that matter, several types of food shrimp are being raised in freshwater despite the fact that they were originally fully saltwater shrimp.

I had to put a heckuvalot of marine salt into my tank before my hydrometer budged above 1.000, if I remember correctly. Once the SG actually registered, it could be altered by varying the salt by a mere teaspoon or two per five gallons.

I think I read somewhere (possibly on this forum) that this was normal.

I've had tiny little shrimp fry turn up in some of my tanks months after any live ghost shrimp or brine shrimp eggs have been present. I'm not sure which particular shrimp they were, though I always suspected ghost. In my Betta tanks, which usually get the tiny shrimp appearances, I don't recall putting in brine shrimp eggs.

Could the tiny shrimp hide out in aquarium gravel, then appear in a new tank with "used" gravel weeks or months later?

....Are you sure they're shrimp fry?

Holy cow...it's been awhile since I have logged in! Just as a refresher I am cycling my tank towards 1.005 BW for the gobies and added some "feeder shrimp" to try to even out the bio-system in there. One of the shrimp was carrying shrimp babies and those were quicly eaten by my 7 gobies (good, cheap meal in my opinion).

When my hydrometer hit 1.0 the water started to cloud...so much so that I was horrified that I may lose my gobies. I did 8 emergency water changes in those three days...adding more FW mix than SW. And luckily I didn't lose a shrimp or a goby during that time although they were all breathing heavy. Today, I did a 30% water change adding (again, which is less than I have been) 1 tsp/gallon of sea salt and the gobies are so happy--swimming around and eating. I just have to say that these gobies are cute, but they are allot of work...very sensitive little fish.

I am still determined to get that tank to BW at some point, but probably more slowly than 0.02/week with I was told was an OK shift. I tell you, I have learned so much about fish in the short time I have been on this website...thanks to all you fish nuts out there!

That's good to know. It's been several weeks since I've been on , too. At least, It feels like several weeks.
