Description
StressGuard is a slime-coat protectant and mild antiseptic. It supports the fish’s mucus layer, reduces stress through handling and transport, and lessens the damage from ammonia exposure while a fish is bagged.
The obvious moment for it is acclimation: new arrivals, a fish that has been netted or moved, or anything carrying scrapes from a chase. It is not a medication and will not cure disease – it makes the fish’s own defences work better while it recovers.
The 4 L size is bulk sizing for a facility handling regular arrivals.

Shipping & Returns
- Equipment and dry goods ship at their own rate. Free shipping at $349 or more applies to qualifying livestock only — corals, fish, inverts and live copepods. The $10 box & handling fee is a livestock packing fee and does not apply to dry-goods orders.
- All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
- Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
- Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
