Customer Reviews
Good value for my planted tank
I was looking for the best deal on some Dwarf Hairgrass and some Aquarium Fertilizer for my new setup. Marcus Fish Tanks had a bundle deal that made it a pretty good price compared to other sites. I also qualified for free shipping, which saved me a few bucks. The plants were fresh, and the fertilizer seems to be working well. I felt like I got good value for my money, especially with the free shipping. It was a solid purchase overall.
Amazing plants!
Marcus Fish Tanks is the best! I got some Monte Carlo and a couple of Marimo Moss Balls, and they are gorgeous. My aquarium looks fantastic now! Everything was packed so carefully, and the plants were super green and healthy when they arrived. I'm definitely shopping here again! You guys have to check them out!
Got some cool stuff
Needed some new plants for my tank, so I checked out Marcus Fish Tanks. Grabbed some Hornwort and a Sponge Filter. It was pretty easy to find what I wanted on their site. Everything showed up a few days later, packed okay. The Hornwort looks decent, and the filter is working fine. Pretty chill experience, nothing complicated.
Consistently good quality
This is my third time ordering from Marcus Fish Tanks. I came back for more Cryptocoryne Wendtii and some Seiryu Stone this time. Like my previous orders, the plants were healthy and well-packaged. The stone was exactly as pictured on the site. Their consistency is why I keep coming back. I know what to expect, and they always deliver good quality, which is important for live aquatic plants. No issues with any of my orders so far, always reliable.
Healthy plants, quick delivery
Ordered Dragon Stone and a couple of Ludwigia Repens. Everything arrived quickly, plants looked good. Happy with the purchase. Will use again for my next tank.
Good plants, average shipping
I ordered a few Anubias Nana and some Java Moss for my 20-gallon tank. The ordering process on the website was straightforward, easy to navigate. I appreciated the clear photos of the plants. Shipping took about 6 days to get to my place in Ohio, which felt a little long for live plants, but they arrived well-packaged. The plants themselves were healthy and vibrant, with good root systems. I followed the quarantine instructions on their site, and they've settled into my aquarium nicely. Support was responsive when I had a question about planting the Anubias, giving me some helpful tips. Overall, I'm happy with the quality of the product, just wish shipping was a tad quicker for live goods.

Share tips, ask questions & help fellow shoppers save more
Are the plants from Marcus Fish Tanks really snail-free? I've had bad luck with other places and don't want to deal with an infestation again.
my plants arrived kinda melted, what's their policy on that? will they replace them?
thinking about getting some stuff, are Marcus Fish Tanks' plants better than, say, Aquarium Co-Op's? pricing looks similar but curious about quality.
Does anyone know if I can use the 10% off first order discount AND get free shipping if my cart is over $75?
Is it safe to order live plants from Marcus Fish Tanks in winter? Worried about them freezing during transit.
