Neptune Aquatics Reviews

I purchased a $32 piece of driftwood with Java fern attached from Neptune Aquatics (see photo), expecting a clean, safe product for my turtle ecosystem tank. What I got was the opposite of quality.• The driftwood continuously shed dark debris into the tank, turning the water murky brown within hours, even after soaking it in potassium permanganate. It severely disrupted my biofilter cycle and beneficial bacteria development.• Worse, the driftwood was infested with pest snails – I discovered eggs and baby apple snails (Pomacea) shortly after introduction. This is completely unacceptable and poses a serious risk to any aquatic setup.• The wood itself seemed untreated, flaky and poorly processed, releasing particles even after rinsing and soaking.I trusted Neptune Aquatics for healthy livestock and clean hardscape, but this was a waste of money and a threat to my tank’s balance. Avoid buying driftwood or any attached plants from this store unless they can guarantee proper cleaning and quarantine.Disappointed and frustrated. I won’t be returning.

Really great selection of fish, plants, and supplies! Bought a couple of leopard cories that are healthy and plants. Really friendly staff, the lady that helped me did an inspection on one of the tanks I was buying to insure I was not being sold a broken product.

Our little 10 gallon freshwater tank is doing great. They helped set up the community tank with neon tetras, corydoras and hillstream loaches. It's been a couple weeks now and it's doing great. Nice helpful staff and all the fish looked healthy and well taken care off. Will be using them again.

Neptune is the only fish store I'll buy from in the bay area anymore. The staff is great - not too overbearing, but helpful enough and friendly when you need to them to be. The prices reflect the broader quality of their stock... I've purchased over 60 tropical fish from this store and have only had one die during the transfer to my tank b/c of genetics or weakness. They have a blog you can subscribe to for all new stocking updates, making it easier to find specific fish you're looking for. Awesome store!

Despite the wide variety of livestock and dry goods, some employees are very cold and do not show any interest in helping or about caring about your concerns. Their attitude is more like “get want you want and go away.” Honestly, I love supporting local businesses but these guys are pushing me to do online shopping instead. I hope they can take this review constructively and improve upon it.
