Description

Fish room doors deserve a firefish goby warning sign, and this one puts the reef’s jumpiest lookout on duty under a bold WARNING header. It’s printed directly on rust proof aluminum that shrugs off saltwater splashes and humidity, and it’s sized to hang above a reef tank stand or beside the sump.

Will it hold up in a humid fish room next to the sump? Yes. Aluminum can’t rust in damp air, and the coated surface wipes clean when salt creep finds it. The 9x12 inch size fits most tank stand doors.

Product Details

• Design: a bold WARNING header, a firefish silhouette and a property protection disclaimer in classic safety sign style
• Printed directly on heavy gauge aluminum, so the image won’t peel or bubble like a decal
• UV protective coating helps the print resist fading in sun or strong light
• Rust proof aluminum that won’t corrode from humidity or saltwater splashes, indoors and out
• Slightly rounded corners and a lightweight build

Size & Finish Options

• Rectangle sizes: 9x12, 12x18 and 16x24 inches
• Square sizes: 6x6, 8x8 and 12x12 inches
• Finishes: Clean, New Look for a modern fish room under bright reef lighting or Distressed, Wood Look for a basement setup with a wooden tank stand
• Mounting: with or without pre-drilled holes, on every size
• Starting at $14.95

Packaging & Shipping

Every sign ships flat in a rigid fiberboard mailer or a heavy duty box to prevent bending. Orders are printed in Henniker, NH and leave the studio within 1 to 2 business days. Standard shipping by USPS Ground is free on US orders of $50 or more and $5.95 on smaller orders. Need it sooner? Choose USPS Priority Mail or Priority Mail Express at checkout. Every order includes tracking, and local customers can pick up at our Henniker studio.

Perfect For

Reef keepers who run a dedicated fish room, frag swap regulars with a firefish pair in the display tank, and anyone who has found a firefish on the carpet because the lid was left open. It brings a little humor to fish room decor without a single extra hole in the tank stand if you choose the no holes version.

Made With Care

Every sign is made to order and handled with special care from printing to packing. Want different wording or a custom size? Email us and we’ll do our best to make it happen.
