How Long Does It Take For Fish Food To Become A Problem?

Today I tried one of those 'tick on the inside glass of the tank treat tabs'

Made by 'Fish Science' (Apparently the guy that set up Tetra or something like that), Fish Treats with Shrimp.

My 40L has 7 Ember Tetras and 5 Salt and Pepper Corydoras (and 2 Assassin Snails).

I stuck it on the glass at about one o'clock, and it is still there. They've had a good go at it, but there is still a lot left.

Should I remove it now? Or tomorrow?

Thanks Sue.

Yes, I've chopped a couple in half to see how they go. They crack and crumble a bit, and I'll have to experiment to see if they still stick when halved. I put a whole one in as the first go just to see if they liked it.

I'll report tomorrow on how much is left.

I might try courgette one day; does it have to be peeled? Does it float about/need anchoring etc?

Thanks Sue

I'll try that.
