Just found another snail in the tank and its deffently some kind of snail. I am as a few weeks ago everything was moved to another tank and i couldn't find any snails (other than the red spotted one). I have a photo and shall upload it, not sure if it will be very clear though as he is tiny.
Yes, looks like a ramshorn to me. You can get pinkish ones but some are just a beigey sort of colour. It looks a lot like the ramshorns in my tank, they stay fairly small and don't breed too quickly if you make sure not to overfeed your fish.
Its a beige (ish colour), have found a couple more too which are a bit smaller.
I have more baby guppies (12 more born last week) but lost a couple adults, my older babys now have colour in their tails and some are blue snake skin so i'm very happy (was trying to get blue colours). Mr Molly is ready to burst so maybe a christmas birth tomorrow.
