Evan Morrison –
Added a Sharpnose Toby to my 40-gallon reef tank. It’s active and doesn’t damage corals. Feeds well on small crustaceans. Needs some space and a stable environment. Good for intermediate hobbyists.
Katherine Marshall –
The fish has adapted well in my tank. It’s semi-aggressive but not overly so. I keep it with larger, calm species. It’s a good addition to a reef setup with proper tank size.
Caroline Ross –
Felt confident adding this pufferfish after reading the care notes. It’s active, colorful, and doesn’t harm the reef. Only needs a balanced diet and regular water changes.
