Lightly Medicated | Rainbow Garra

What “Lightly Medicated” means

This is the same animal as our non-quarantined listing, held briefly in our systems and given one short prophylactic course — a light treatment for ich and for internal and external worms — then observed eating in front of us before it goes home.

A light course knocks the parasite load down. It does not guarantee full removal, and we will not pretend otherwise. Ich is only killed in its free-swimming stage, and a short treatment window can miss cysts entirely; worm burdens can survive a single dose. Clearing an animal takes the full quarantine window — 40 to 90 days depending on the species — which is exactly what the Quarantined listing is for. This tier buys you a lower parasite load and a fish we have watched eat, not a cleared animal.

We condition the fish on our end. Every animal we medicate is brought back onto prepared food on our own systems and is eating before it leaves — in practice it is rare for a lightly medicated fish to ship out and arrive sick. Do the same at your end: get it eating in your aquarium before you count it settled.

When it ships

Plan on 3–5 days on our systems for the treatment course, and it does not leave until it is eating. If the animal is not already in our systems we source it first — allow up to two weeks for it to reach us before that clock starts. From the day you order, plan on roughly two and a half weeks in total.

The guarantees

• Shipped orders: 24-hour live guarantee from confirmed delivery.
• In-store pickup: 7-day live guarantee — bring a water sample from your aquarium so we can test it before your livestock goes home with you.

Want the full program — treated, observed, confirmed eating, and covered for 28 days on pickup? That is the Quarantined listing. Run your own quarantine and just want the fish this week? The non-quarantined listing is cheaper still. The whole ladder is explained in Quarantined vs Non-Quarantined.

Garra species are the same genus behind “doctor fish” — the small freshwater cyprinids used commercially to graze dead skin off the feet of spa customers, a service made possible by a specialized ventral sucker disc that lets them clamp onto hard surfaces in fast current and work them over methodically. The Rainbow Garra brings that same biomechanical toolkit, with a more colorful dress: iridescent blue-green and orange tones across a compact, torpedo-shaped body adapted for life in fast-flowing water.

In a tank, they’re perpetual-motion algae grazers — give them rock surfaces, driftwood, and decent water movement and they’ll work the same patch repeatedly, rarely sitting still. They’re most active and show the best color in aquariums with meaningful flow; a still-water setup dulls their color and behavior noticeably. Compatible with most community fish their own size, though they can become territorial with their own kind in tanks where there isn’t enough rock territory to go around.

Scientific name: Garra sp. (Rainbow Garra; several species sold under this common name, including G. flavatra)
Origin: Fast-flowing rocky rivers and streams of Southeast Asia — Myanmar, Thailand, and surrounding highland stream systems
Water parameters: Temp 72–79°F · pH 6.5–7.5 · GH 5–15 · Good water movement preferred
Tank requirements: 30 gal minimum; rocky aquascape with strong current; cover the tank — these fish jump
Diet: Herbivore/omnivore — algae, biofilm, algae wafers, blanched vegetables; occasional sinking protein
Compatibility: Semi-territorial with own kind; peaceful with most similarly-sized community fish
Husbandry note: Rainbow Garras kept in low-flow tanks lose both their color saturation and much of their behavioral interest. A powerhead or strong canister filter return pointed along the glass is the single most impactful environmental change you can make for this species. Match the habitat — fast highland streams — and they’re a completely different fish.
