I was looking for those granules, but instead I found This. The fish innitially didn't quite recognise it as food, but that problem is over now. smile One of those multy food thingies would be very usefull if I can find it. I also bought the shrimp. I went ahead and bought 5 and it's working out great! 4 of them are amanos and they love hanging around together on the wood near the surface plucking at algea. The fish don't really bother with them at all, appart from nudging them away when they want to graze the same spot. The 5th is not a amano, I think it's a ghost/glass shrimp. It's appendases are longer and thinner and it has that hump. It's quite large and solitairy, generally keeping to the lower waterlevels. It also barely grazes for algea, preferring to perch somewhere with it's claws extended outward. It's also a bit more agressive, it chases the fish away if they come near to it, though not actively. I feel this behavior is a bit more on the predator then the scavenger side. Should I be worried? I don't know much about shrimp since the last time I tried keeping them my betta ate them all. The strangest thing is that that store only sells amanos. They used to sell cherries but they were sold out. I've been monitoring the store for a month or so and never saw them stock ghosts. :/

Oh and also the ghost isn't too fond of light and only becomes really active after dark. It's eyes are also larger and stick out more then the amanos.

thats weird for the shrimp
i dont think its predatory though. doesnt sound like it has any unusual claw formations or anything. and even lobsters who have huge clawsare still scavengers.
the only predatory shrimp i can think of right now are pistol shrimp (and only certain kinds) and mantis shrimp
it may be trying to clean them? i dont know of any freshwater cleaner shrimp but i know saltwater cleaner shrimp LUNGE at fish and all they want to do is clean them
just keep an eye on it. and if you dont like his behavior just take him back. no point in being all worried over it especially in a smaller tank

I have been doing some research on shrimp and I am a tad worried. I think it might be a juvinile of the macrobrachium family, which is related to the normal ghost shrimp, but grows larger and has clawed arms. Especially in the male. I found two reffence pictures I'm using. Normal Ghost/Glass shrimpJuvenile MacroThese shrimp are apparently rarely sold in aquarium stores, but mix ups have happened. Not all species prey on fish or other shrimp, but just as many (or more?) do. Info I found on the species in general: Quote: The Palaeomonidae family contains at least four genii that might be familiar to aquarist; Macrobrachium, Palaeomonetes, Palaemon, and Leander... Palaeomonetes have been accused of catching small fishes and fry (?). My experience, however, leads me to believe otherwise. I would guess that the fish catching shrimps probably belong to the genus Macrobrachium... Macrobrachium are freshwater prawn that are often commercially raised as a food fish in many part of the world. Many different varieties exist. Macrobrachium is seldom seen in the aquarium, and then probably only as a novelty item. It gets too large for most planted aquaria and can cause damage to both plants and fish due to the existence of large claws on dominant adult males. The name macrobrachium actually means "big arm." SourceQuote: Larger shrimp, such as Amano (Caridina japonica) and the smaller Macrobrachium species (such as the Vietnam blue) can be mixed in with larger fish such as swordtails, platys and the like. Larger Macrobrachium species, like the red-spotted and red-claw, are best kept in a tank of their own as they can capture and eat small to medium-sized fishes (at worse) or mutilate fish... When it comes to the long-arm species, there is a definite possibility of shrimp predation. Long-arm shrimp (Macrobrachium spp.) may eat smaller shrimp species and conspecifics... The pearl shrimp (Macrobrachium luzifugum), being a substrate dweller, should be fed more of a meat-based diet (tablet foods are good for this), although flake food is also readily taken. Larger Macrobrachium species will feed upon frozen foods such as mysis or bloodworms (as will the afore-mentioned shrimp). They may also catch and eat smaller fish... SourceI also managed to snap some pictures of the shrimp which 'seem' to confirm my suspicions. 1. 2. 3. 4. I'm going to the petstore later today to ask if they ever carried any Macros. On a brighter note the fish are doing great, last night I even saw the male 'dancing' for the female. He had more color then usual and would pose vertically infront of her and dart away a short distance if she approached, trying to lead her around the tank to his favorite spot. He hadn't build a nest though, and she wasn't quite that interested, still, I was surprised to see this behavior only two weeks after purchase. This morning he was back to his usual snippy self though ^^; Here are some pictures: Male & Female, with mystery shrimp in the background on his favorite perch.Female with Amanos hanging from driftwoodMale

Well, the pet store was closed yesterday, and it will be friday by the time I have a chance to visit the store again, maybe wednessday with some luck.
Meanwhile I'm 90% sure it's a Macrobrachium. One of the defining characteristics appart from the arms is a serrated rostrum (ridge/nose between the eyes), and it has that.
At 4 cm it's no danger for anyone for now, but unless I know which species it is I won't know it's maximum length or true temprament. The amanos are afraid of it in the sense that they pointedly avoid him. They seem to fear it more then they fear the gouramis.
I'm nt quite sure what to with it honestly. It will be hard to catch since it lives in the drifwood that's supper glue'ed to the tank, and I actually kind of like 'agressive' scavengers. It reminds me of the fidler crabs I used to own. If my tank was larger I would have no doubt in keeping it, but since I also hope maybe to breed the gouramis some day it will probably have to g evenually.
I'm thinking that when it gets larger I'll probably fish it out and give it a small tank of its own on my desk or night stand. And if I really can't handel it I'll try to sell it or cook it. (I read on a few pages that these shrimp taste good redface )

Ah, it's time to resurect this thread, do forgive me for letting it die ^^; I'll post a little vid of Murphy and Sod's antics, and maybe later I'll post more pics. I've got pics and info in the first post. @skittles: The shrimp is just one of those creatures with a permanent bad mood, and appart from Sod who lost a few scales, he hasn't hurt, or been able to hurt anyone. The others in the tank just steer clear of him. If he actually is a macrobrachium instead of a gost, then it's prolly a female of a small species.

I have ghosties, they are naturally aggressive like that but they don't grow too big so it's never been a problem for me. I think it's cute that they're so small and invisibleish and yet they have such huge personalities.
Very nice tank.

Thank you smile Yeah, the personality of the ghost really surprised me. Since I heard of them being used as feeders I thought they'd have the typical 'prey' behaviour. And when I found out that sometimes macrobrachium juveniles got sold as ghosts I kind of panicked. Shrimp really aren't well documented. Which reminds me, one of my amano's turned redish. Probably due to the amount of wood in there, or because I started feeding them more bloodworms so the fish could survive the fasting they'll have to face during my vacation.

That must be an interesting sight!
I think my crays ate my ghosties, I haven't seen them around. That's just adding to the fuel of me getting rid of them. They ate my betta last week.

Well, my attempt to place a devider is failing misserably, so I'm keeping the agression down by feeding no more bloodworms and using the filter to create more current.
It saddens me that I can't see the pretty colors anymore sad
Strangely enough one of the amono's and the ghost shrimp are berried. The amano I understand, since there is a male in there. But I only have a single ghost? Can they fertilise themselves?

I've never heard of that happening with ghosties, but it could be possible. Another possibility is that the shrimp crossbred or that she was fertilized when you got her.
For bloodworms, try feeding in multiple areas of the tank to reduce aggression. I use a turkey baster to spread the worms all throughout the tank, that way everyone gets some.
