Does he not chew on corals and invertebrates Simon being a pufferfish ?
How to explain, great question by the way, I do impulse buy but backed up by research.
Due to how I run the tank fish really need to "fit", I rarely buy carnivores now, the fuzzy dwarf lion is because I love them, it eats flake as well as being target fed frozen 2 or 3 times a week.
The puffer is listed as an omnivore.
I watch fish to see if they still have their natural grazing instinct, if they just swim around waiting to be fed I won't buy them.
It is one of the smallest puffers and started grazing rocks about 40 minutes after introduction.
Yes it is a risk but a small one in my opinion!
I share my experiences with Siporax - hope you do not object najer.
I used Siporax in a anaerobic environment and I got very high Si readings – over 17 000 microgram/l. I have take them away and now my Si levels read 400 microgram/l. It looks like there is no issue as long as they are aerobic (get oxygen) but during anaerobic conditions – Siporax release Si to the water column
By the way - Beautiful tank Najer

Always feel free to add to my journal.
I am going to remove it over the weekend, been thinking about it, your comment sealed it, thank you.

I always put it in as a backup, currently I appear to be in a lower nutrient phase, slowed macro algae growth.
I need to get some water from the lfs first as when I remove it I want to rinse it to save the pod life.
(No I don't keep salt in the house.)
Thank you.
