Not a very sharp photo, but the body reminds me a little of brine shrimp, except it doesn’t appear to have a tail.

 

[sparkyweasel]

Could be an isopod, Asellus or similar. In which case it's harmless.
A better pic would certainly help if you can manage one.
Have a look here and see if it looks similar.
Asellus

 

[Tommythefish]

Nice one pal.

 

[sparkyweasel]

That's better, and the coin for scale is good.
I still think an isopod of some sort, Asellus or one of its relatives. Probably came in on some plants, maybe when it was tiny. Could be a foreigh species, depending on where your plants were grown.

Rather looks like a snail leech to me. Look up some photos and it would be easy to identify it in person.

 

[Tommythefish]

Nice one you beautiful people I very much appreciate your wisdom, yh thought as much all my tanks are planted. Plants from maidenhead aquatic. Just to be sure it isn't a parasite and I can put it back in the tank.

The dark pattern looks like a branched intestine so my guess would be some kind of flatworm, possibly a planarian but there are thousands to choose from. It's probably harmless unless you are trying to breed shrimps, and any fish big enough would happily eat it.

 

[sparkyweasel]

Can you see if it's got lots of legs?

Can you see if it's got lots of legs?

Hang on.

Yup i can confirm critter in question has lots of legs.

 

[sparkyweasel]

OK, that rules out leeches and flatworms.

Looks like some sort of Nymph!

Hi all,

Looks like some sort of Nymph

Assuming they are legs (and I'm still not entirely sure), there are too many for it to be an insect (they have 3 pairs) which makes it a crustacean, and most likely <"Asellus">.

Zoomed in on the photo and for me that's a Snail Leech

 

[dw1305]

Hi all,

for me that's a Snail Leech

That was my first thought and that the "legs" are the branching intestine.



cheers Darrel

 

[sparkyweasel]

Oops, I though it was the OP confirming the legs. Can you get a good look at it @Tommythefish ?

 

[Jaseon]

I thought it was legs as well.

Im going with snail leech, and my decision is final

 

[Tommythefish]

Thanks fellow fish keepers. @dw1305 that's exactly what it is. Very much appreciate. What can this beast no to my shrimp

 

[MirandaB]

Probably unlikely to harm shrimp although I can't say for certain.
I get some monster snail leeches in the river at the bottom of the garden during the Summer but they mostly seem to be feeding on detritus collected in the Nuphar leaves......or they might be hunting for snails lol

 

[Tommythefish]

@MirandaB That's a relief. Nice one pal , I put it back in a tank of its with some snails justing case. All the best. Six Nations 🏴󠁧󠁢󠁥󠁮󠁧󠁿 🏴󠁧󠁢󠁷󠁬󠁳󠁿
