Damselfly Nymphs?????????

Recommended Posts

keego

Just found and removed about ten of these bastards in my 3ft divided tank. Bad news is had berried snowballs all release last week. Cant see any juvries now [don't swear, stay clam]. Do these things kill full, grow shrimp, as I've loosed 3 pair of dark blue cherries, were there 4 days ago??[don't swear, stay clam]

So should I reset the tanks, remove all water & start again. The tanks is in a rack of 9 tanks???? how do these get into a tank, I take it they likely to spread.

Any advise

Thanks

Were any new plants, rocks....intriduced.....Damn, they're nasty....never had one in my tanks before (touch wood), and I'd definitely make sure they're all nuked. Lots of tank staring over the next few days.....if they're only in one tank, I'd quarantine :-)

I had a few turn up but never did find the source. I found them by noticing some folded leaves floating through the water un- naturally and had to investigate why. They were still pupae at that stage and found in mulberry leaves but not sure if that's how they were introduced.

quite often they come in on plant's as most plant w/saler's grow in outdoor pond's.

Oh no dude! That's terrible news!! I once had them in a tank & they had been laid directly into the water(but I found the damselfly in the house), there were heaps of them in the tank & they were under everything! Ended up stripping everything out of the tank back to the gravel & water & catching them myself. Definitely not something I every want to happen again. :dejection:

You should always boil IAL, you never know what nasty stuff they have on them

I boil mine for a few mins enough to kill anything alive on there :D

Bit of an update, at my expense!!!!!!!!!. Check the tanks this morning & found 4 adult damselfly attached to the underside of the light. Thinking that good, only to find another 4-5 attached to the inside of the glass, just about the water line. Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh, that hurts. So going to have to research the life cycle of this little bugger. Got a feeling Im going to be catching these for the next couple of weeks.

Ouch!

Needless to say, you have to get rid of them asap.

In the wild these bas@#@rds feed on daphnia, mosquito larvae, and various other small aquatic organisms.

Unfortunately, in an aquarium or shrimp tank, the lack of these food sources mean that they will prey on any tank inhabitant, that strays near them.

If you can, take out all tank decorations and plants and inspect for these buggers.

A cleared tank will help you find them easier too.

See the prongs at the end of the tail? That's their breathing apparatus. A bit like a snorkel. They sometimes hang upside down at the water surface to breath when there is a lack of oxygen in the water. That's when you catch them.

However, in a tank with shrimp, oxygen in the water column might not be lacking. So they stay submerged longer.

If they are not on the water surface, they are hiding under leaves.

Often they bury themselves in the gravel too.

A light gravel vac might suck some of them out too, if they are hiding in the gravel.

At least you get a water change chore out of the way at the same time.

Good luck. Use a bright torch to try spotting them in a bare tank.

      I hope you can feed them. I kept pipefish for a while but had enormous trouble feeding them.  They wouldn't take any prepared foods and are massive predators so I was feeding them all my small fish and all the shrimp I could throw at them.    When I got them I thought they'd eat fresh hatched brine shrimp but no they wanted MUCH bigger.   They both jumped out of the open top tank.

      DAS are very robust and I've kept them in a tank with Melbourne tap water and in rainwater with  DIY hardness booster.  You'll find them in Northern Australia in both the fresh and brackish sections of rivers so they have really wide tolerances.  My tanks range from 24C to 29C If you get some keep the covers on for the first 2 weeks as they can be jumpy if your water parameters are a long way from what they were housed in. After a couple of weeks they settle down and rarely jump.  I know some people with open tanks put gladwrap over the top for the first couple of weeks only. I'll also suggest that no-way will they interbreed with your Tangerine Tigers -  they are very different shrimp and their bits wont fit together even if they were so inclined.   If money is tight then Paratya are about half the biomass but will breed up easily and also wont cross with the TT .... or do both.  You can keep all three together in the same tank.

      Idk my tds but the rest sounds similar to my tap. If Grubs uses just dechlorinated tap water too then we probably would have the same parameters as we’re both in melb. And that’s my normal temp as well.  How do you keep them @Grubs?

      I would get a few if you like them, the odd loss of a baby shrimp wouldn't really be a problem. There are lots of shrimp people that have the dwarf Corys with their shrimps.As you say, it maybe better to wait a bit until you have more shrimps first but the cory doesn't hunt shrimps as food!

      I think that the shrimp in the photo is a female! Great you got the slots sorted so quickly and easily. The good thing with the amano is that they won't breed so you will never get more than you buy. Don't get too many though (may be the 5) as they are bigger and will out compete the cherry shrimps for food. Don't forget that there is postage cost with ProShrimp below £39 (I think that is the figure??) so bear that in mind as if you are close to that and you buy a few more shrimps you will get more shrimps for the same cost by not having to pay postage - f that makes sense? The other option is the tangerine tigers as they won't cross breed with cherry shrimp but you get a different colour - those are out of stock at the moment though! You need to be at home next day to sign for the package. https://www.pro-shrimp.co.uk/tiger-shrimp/563-tangerine-tiger-shrimp.html Simon
