👍 Pros
- All-natural formula with no artificial colours; pigments come from real ingredients
- Added garlic makes it extremely palatable — useful for tempting reluctant or new fish
- Marine-protein base gives strong growth and colour as a near-complete diet
- Dense pellet holds together well and clouds the water far less than flake
👎 Cons
- Premium price per gram versus a basic flake or pellet
- 1 mm pellet is too big for the smallest nano fish and fry
- Sinks quickly, so surface-only feeders may miss it — target mid and bottom fish
A near-complete pellet
New Life Spectrum Thera+A has a reputation as one of the closest things to a single-food complete diet, and the formula backs it up: a base of quality marine proteins — antarctic krill, herring and squid meals — with natural colour enhancers instead of dyes, plus vitamins and garlic. That garlic is not a gimmick; it is a powerful feeding stimulant, and it makes this pellet the one that reliably gets stressed, newly added or fussy fish to start eating.
Dense, clean and easy on the water
Because the 1 mm pellet is dense and holds together, it clouds the water far less than flake, and it is easy to portion: a little looks like a lot. That density is exactly why restraint matters. Feed only what your fish clear in about two minutes, once or twice a day, and lean toward too little. Uneaten pellets sink, rot and drive ammonia and algae — the usual culprits behind a struggling new tank. A weekly 25–30% water change, with a gravel vac to lift any leftovers, keeps things in balance.
How it fits with our other picks
Thera+A works well as the staple for medium community fish, small cichlids and livebearers; the 1 mm size is a touch big for the smallest nano fish, so pair it with a micro food like the Hikari Tropical Micro Pellets in a mixed tank, and add Hikari Algae Wafers for bottom-dwellers. For the full range and how to match food to your stock, see our fish food hub; match your fish to the tank on the aquariums page; and track nitrate with a kit from the water testing hub.
The pellet to reach for when you want one high-quality staple: all-natural marine proteins, natural colour and garlic-driven palatability that gets even shy fish eating. Premium priced, but a little goes a long way.
New Life Spectrum Thera+A Regular — frequently asked questions
Why is there garlic in the food?
Garlic is a strong feeding stimulant and is widely believed to support fish health. In practice it makes the pellet very palatable, which is genuinely useful for tempting newly added, stressed or fussy fish to start eating.
Is Thera+A really a complete diet?
It is about as close as a single dry food gets: a marine-protein base with natural colour enhancers and vitamins. Even so, we still recommend some variety — the occasional frozen or freeze-dried treat and a food that suits any fish the 1 mm pellet is too large for.
How much and how often should I feed?
Only what your fish finish in about two minutes, once or twice a day. The pellet is dense, so far fewer are needed than it looks. Overfeeding rots on the substrate and drives ammonia and algae, so vacuum leftovers during your weekly 25–30% water change.
