My betta has been struggling with water changes and new tank setups. Since switching to Thera+A, it’s eating more and seems calmer. The garlic scent is noticeable but not overwhelming. Good for new fish introductions.
Simon Parsons –
Used this for a newly acquired guppy. It adapted faster than before and started eating within a day. The texture is smooth and the fish seem more active. Would recommend for stressed fish.
Joanne Black –
Great for transitioning fish between tanks. My corydoras stopped hiding and started feeding regularly after I switched to Thera+A. The added nutrients seem to help with recovery.

It works for some fish, but not all. My shrimp didn’t show interest. Still, the fish in the tank seem more active and less stressed. May need to pair with other foods.
