To update the thread, I could not find 3mm pellets of NLS in all possible online shops at this side of the pond..One of the biggest aquatic shops in here has been "out of stock" of these for the last few years lol. Small shops here never even stocked NLS...what a pity...I ordered 2mm algae ones but my clown loaches can swallow the 3mm whole with no problem, except for the new baby loach.... but he bites them and carries them away to eat in peace...plus he also eats with the denison barbs and SAEs during the day so no fear for him...
