The Puffer Forum

I have a rather large colony of ramshorn snails in a 40l tank.

My question is how many is too many, I reckon I have over 100.

Up until today the tank has been cycling ok with no real spikes in ammonia or nitrite but today ammonia was up into toxic levels, nitrite had also gone one up on the scale.

I've done a large water change and put some prime in just in case the snails aren't as bomb proof as I thought.

I'm just worried the filter won't be able to cope with so many, obviously when I get my puffer he will cull the population.

I say keep up the good work, snails will survive some swings and your population will start to regulate once you have your puffer. Step up your maintenance on this tank to keep the population thriving and perhaps set up a tub to move some into, you can't really have too many. Perhaps reduce feeding slightly or feed easily removable foods so you can let them eat and reduce the waste, a lettuce leaf or similar should work

Awesome thanks Bertie. If I transfer some to a bucket will they remove themselves if it doesn't have a lid? I'm tempted to get another tank but it seems a bit overkill lol

God they proper love courgette and cucumber don't they! I've got them little mineral blocks with spirulina in too!
