    Today was the first time I’ve been able to login for about a month.  There’s still something fishy, (pun intended), going on because the site looks weird….. the formatting is all off.

    @matt said:
    Very nice Dennis! I have never heard of this trick before, what is the theory behind it?

    Basically what plesner alluded to…..

    The release of hormones, pheromones, or some other chemical(s) into the water aids in triggering the fish to spawn.  I don’t have any science to go with it or prove / disprove that it works, just an old fish breeders trick that I picked up somewhere over many years of fish keeping.

    My vote would be for Otocinclus mariae.  Looks similar to te ones I worked with here ==>> http://www.seriouslyfish.com/forums/freshwater-and-brackish-water-fishes/spawning-otocinclus/

    The middle fish in the photo is the Otocinclus mariae, the other two are the Otocinclus vestitus.

    Thanks Bill.  I see the Wet Spot has Devario maetangensis on their stock list.  Most of my really cool Danionins have come from Stephan at Swiss Tropicals, the Wet Spot out in Portland, or Pete Mang on AquaBid. Of course, I got those Devario assamensis from you too!

    Well almost 18 months after spawning these fish, I have finally taken a decent photograph of them.  LOL

    F1 Devario xyrops

    I’m hoping to see if the captive bred ones are easier to spawn than the wild caught fish.  At any rate, I now have enough fish to form some opinions about them.

    I would change most of the water or take the mulm from the bottom of the tank and put it in a new container.  If the conditions are good, the ephippia should hatch within 4 to 8 days.  Of course, if you accidentally poisoned the culture they may not be able to make a come back.  Daphnia are very resilient, and can often rise from the dead like the mythical Phoenix.

    Best of luck getting your culture back.

    I feed mine a combination of dry pea flour, spirulina algae, cholera algae, active dry yeast, a pinch of paprika and green water.  I feed twice and on the third day harvest and do a large water change at the same time.  With four cultures running I get a large daily harvest.

    Thanks for the link Bill, it looks like a site to watch.  Nice easy reading with the clean layout.

    It’s been my experience that you run a greater risk with frame-less tanks.  I have had frame-less tanks open at a seam and drain rather quickly, while tanks with intact frames that prevent the glass separating at a joint, only develop slow leaks as mentioned previously.

    Give your shrimp lots of cover and you should be able to maintain a modest colony.  In my experience even the tiny Danios like margaritatus and erythromicron will hunt baby shrimp, but given enough cover the adults should be OK.  Often with larger fish in the same tank, the shrimp become so stressed that they do poorly, even if the fish do not try to eat them.

    Well the fry are around 3 months old now and starting to look like miniature adults.

    Acrostomus fry at 3 months

    It’s been a very cold winter here in Ohio and temperatures in the fish room have been on the chilly side. This may have lead to the fry growing at a reduced rate.

    Devario acrostomus adults

    The adults have continued to spawn on a somewhat regular basis and there appears to be a small number of fry from 3 or 4 different spawns living with the adults.
