Due to the nature of live aquatic animals, all livestock and plant sales are final. We do not accept returns or exchanges once fish, invertebrates, or plants have left our care.
Livestock at Pickup
All livestock is inspected prior to sale and provided in good condition. Customers are encouraged to inspect their fish, shrimp, or snails at pickup and raise any concerns before leaving.
Once livestock leaves our care, Ottawa Tropical Fish cannot control transportation, acclimation, water parameters, tank conditions or interactions with existing livestock. For this reason, we cannot guarantee livestock after pickup.
Ottawa Tropical Fish is not responsible for losses resulting from:
Improper acclimation or sudden changes in temperature or water parameters
Poor water quality, uncycled aquariums or unsuitable tank conditions
Aggression, predation or incompatibility with existing tank mates
Improper care after pickup
Live Plants
Plants are provided in good condition at the time of pickup. Some melting, leaf loss or changes in appearance can occur while plants adjust to new water parameters and aquarium conditions. This normal adjustment is not covered.
Please contact us before purchasing if you are unsure whether a species is suitable for your aquarium. We are happy to help with compatibility and care recommendations.
