I have recently been finding these snails in my tank (see attached photo), whilst not a problem now, I have had snails in the past that took over a tank, and practically ruined it, so want to know if i need to take action before it gets to that stage.

Can anyone identify what this snail is, and is it a nuisance snail?

Thanks in advance.

Based on the picture I think it's either a pond snail or bladder snail.
As for being a nuisance, they CAN be, but not necessarily if you control their population. They can clean the tank by eating algae, fish food, and fish waste but if the population increases too much due to excess food it causes increased waste and disrupts the nitrogen cycle.
They can reproduce rapidly if you overfeed or neglect tank maintenance. Just avoid overfeeding, clean the tank regularly, or maybe introduce snail-eating fish to control the population.

It’s not a pond or bladder snail, they don’t spiral like that.

It might be a MTS.

Thanks, always trying to learn more!
 
I agree with Mermegan . They can take over like bladder or ramshorn snails. Limit extra food and they shouldnt get too bad. MTS are good for aerating the substrate, bladder and ramshorn clean plants pretty good.
 
It’s very likely to be one of the Melanoides, but there are over 40 species of them and some are noted for variability in shell colouring.

The Red-rimmed Melania, M.tuberculata, is probably the most common one we see & an unfortunately invasive pest in many places, but there’s also M.maculata, which is dark brown to black in colour & has sharply squared off angles on the whorls, like the one in the image.

The image is definitely not a M.tuberculata.

Thanks for all your replies. I only feed my fish twice a week, so hopefully they won't be a problem. Just in case, I've added 5 assassin snails to take care of the population.
 
Looks like a trap door snail. I don't know scientific names, but also called Chinese mystery snail
Snails tend to have a lot of similarities but this one has those sharp squared off angles on the edges of the spirals, which are not seen in trapdoor types as theirs pare very rounded, no sharp angles anywhere.
 

Random Great Topic!
