    Opae Ula anyone?

    Hello Scapers!

    Anyone here has Opae Ula tanks? I'm in the process of setting up two little 3.7g tanks, wanted to reach out here prior to try and buy macro algae, snails and shrimps online. I'm probably a month out prior to adding in shrimps. Would like to add in some macro algae after the holiday weekend coming up. Thanks!

    I tried googling "Opae ula" but all of the links seem to assume you already know what one is. I am gathering that is saltwater shrimp-only?

    I believe Petshrimp is local from Mustafa, I saw some on ebay, and some from Hawaii sites. Not sure yet.

    I have some! I ordered mine from shrimpmart. He is located in Hawaii, but he has temporarily ceased selling due to earthquakes. I have my SG around 1.011. As far as I know, the only ornamental macro algae that will survive that salinity is the fine threaded species of chaeto. I've tried several others including gracilaria and caulerpa with no luck. From what I read, there are FW plants that can survive in that SG like anubias, java fern and moss, and vallisneria.

    Most moss will die, I never found any that would sustain. Anubias nana gold, java fern are the only plants people had luck with. Everything else melts once placed in high salinity.

    I used to have 300 in a gallon jar with a little puck light bulb I could dim.
    and indirect sunlight for algae growth.
    1.012sg
    78F
    larger black lava rock pieces and smaller crushed black lava rock substrate.
    fed them powdered spiralina.

    I would suggest the black lava rock over the sand, since it's their natural habitat.

    Here's the guy I bought them from back in 2008 (if he's still at that email):
    Jojo Raquel [mailto:aquascapes@mac.com]
    he's on Oahu somewhere, so your Opaes would be from Oahu.

    If you provide a decent environment, they'll spit out babies from time to time.
    good luck.

    I have a brackish tank with puffers. My salinity varies between 1.004 and 1.010. I have an amazon sword, fissidens fontanus, mini xmas moss, and java fern in there. When the salinity is higher the amazon sword and fissidens seem to be more just survivng than thriving, but everything shows new growth when the salinity is closer to 1.005. I haven't tried other plants but I have heard plants that do well in brackish water are Anubias, Valisneria's, Moneywort (Cabomba), Hornwort (Myrio/Foxtail), Java Moss, as well as Calaglossa (Red Moss/Macro Algae).

    The Opaes only reproduced when the algae bloomed, the salinity was >1.010sg, and when I gave up on plants altogether.
    FordTrannyman gave me some African brackish plant... I forgot the name... and that was the only stuff that hung around in higher salinity.
    But it only hung around for months.
    It didn't thrive and the Opaes were happier when I ditched it.

    Well there is another plant option that is used in saltwater aquariums if you don't mind emergent growth above your tank line.....Mangrove.

    I was looking at mangroves as well but these tanks are on my rack so I don't have head clearance for the plant to grow. From everything I've read these shrimps are fine in brackish water from 1.008 to 1.01, marimo moss ball can handle 1.008

    I have also heard Crypts can survive in brackish water, haven't tried yet myself.

    Waiting for the tanks to cycle gonna leave some time to read up some more. For now I might try that fine threaded chaeto on petshrimp.

    Why has no one tried to transition them to freshwater? I mean you'd have to do it slowly over generations... do they have a larval stage?? I should really be googling this before typing, but... but... coffee is controlling functions instead of brain right now.

    Yeah I read about the larvae stage... got me thinking about the amano's and nerite's need for brackish water to hatch sooo... something to toy with. You need a true saltwater tank as well for the larvae to grow out. Then it got me thinking, I really need a saltwater tank of course. Lol. Just never ends. I started with two little tanks, now I have oh 18?
