Frequently Asked Questions
Quick answers to questions we hear from freshwater fishkeepers every week.
When do new fish arrive?
New arrivals are posted on our New Fish This Week page as the weekly inventory is prepared. Availability changes quickly, so the list shows what was available when it was updated.
Do you hold fish for customers?
We do not place general holds on livestock. Special orders are handled separately. If a fish is on the weekly list, it is available until it sells.
Do you take special orders for fish?
Yes. Ask our team about the species you are looking for. Availability depends on our suppliers, season, and the health and quality of the livestock available to us.
Do you guarantee livestock?
Fins For Grins offers a 7-day livestock health guarantee. Ask the store team for the current requirements and exclusions before purchase.
Do you test aquarium water?
Yes. Bring a water sample to the store and our team will help review the results. A fresh sample in a clean, sealed container gives us the best information to work with.
What should I bring when asking for help with an aquarium problem?
Bring your aquarium size, temperature, recent water test results, current livestock list, and photos when helpful. The more information we have about the aquarium, the better guidance we are able to provide.
Do you help with fish compatibility?
Yes. Bring your aquarium size, temperature, water parameters, and current livestock list. We will help you evaluate compatibility before adding new fish.
How many fish should I put in my aquarium?
Stocking depends on much more than gallons. Adult fish size, behavior, swimming space, filtration, water quality, and the species already in the aquarium all matter. Ask our team before relying on a simple fish-per-gallon rule.
What freshwater fish are good for beginners?
Good choices depend on your aquarium size, water conditions, and the community you want to keep. Our team will help you choose fish suited to your setup instead of recommending one species for every beginner.
Do you sell live aquarium plants?
Yes. We stock freshwater aquarium plants, with selection changing as new shipments arrive. Check the weekly arrivals page or visit the store for current availability.
Do you sell shrimp and snails?
Yes. We regularly stock freshwater shrimp, snails, and other cleanup-crew livestock. Species and colors vary from week to week.
Do you sell aquariums and aquarium supplies?
Yes. We carry freshwater aquariums, filtration, lighting, food, water care products, substrate, decor, plants, and other supplies for new and established aquariums.
How often should I change aquarium water?
The right schedule depends on stocking, feeding, filtration, plant growth, and water test results. Regular partial water changes are an important part of freshwater aquarium care.
What is the nitrogen cycle?
The nitrogen cycle is the biological process that converts toxic ammonia into nitrite and then into less harmful nitrate. Establishing this biological filtration is one of the most important steps before fully stocking a new aquarium.
Do you offer aquarium maintenance?
Yes. We provide local freshwater aquarium maintenance for qualifying homes and businesses in Broken Arrow, Tulsa, and surrounding communities. Services include routine water changes, testing, cleaning, filter care, equipment checks, and livestock observation.
Do you install aquariums for businesses?
Yes. We plan, install, stock, and maintain freshwater aquarium displays for offices, lobbies, waiting rooms, and other business spaces in the Tulsa area.
