New Clone Without Black Pigment!

Have had Marbleds since last winter. Have gone through several generations but with considerable losses until I realized what they need! They absolutely need space! Adults and sub-adults need to be separated. Am not sure when the best time to separate the immature…however considering how some of the young are more often apt to attack any of the others while the “others” are more interested in just getting to the food.

It is my best guess that this would be a good time to either introduce them to a much larger tank or perhaps separate the “aggressors” from the others.

Best Experience Ever!

I don't think that I have ever met anyone as knowledgeable as Mark — he really knows his crayfish. I learned more from him in a 10 minute conversation than I would have ever learned from any forum or pet store clerk. The crayfish themselves were beautiful and are thriving. I just can't wait till I have a colony of my own. Thank you Mark!

Rescued! Thank You So Much.

We were in desperate need of restocking our marbled crayfish colony. After successfully raising marbled crayfish for the past two years, we were experiencing a die-off, and badly needed to replenish in order to carry on our experiments in the lab.

Mark Robbins came to our rescue in so many nice ways! It was a pleasure to interact with him via email. Within an hour of our request, he responded and proposed a plan for shipping the crayfish to us. They arrived the next day, in absolutely perfect shape, accompanied by an email with helpful suggestions to continue their good health. Our colony has started again; we will continue to use this very reliable source for marbled crayfish.

I drove an hour out to go get some crawfish — this man met me inside the Whataburger. I got them and drove all the way home and they lasted just fine. They are loving the tank I put them in, now I'm just waiting for them to start multiplying.

Complete Start-Up

Mark is a complete gentleman and a pleasure to do business with. He responded to every email very rapidly. I am a local guy and was very happy to meet in person. He had more knowledge to share and was very happy to answer any questions that I had. I found his website very informative and followed his recommendations for a tank setup, and the marmorkrebs seem very happy. I can't wait to see them multiply and thrive.

Four Crayfish For Aquaponic System

Picked up four 1.5 inch marbled crayfish from Mark on May 1st. I was very impressed by the way he had all four in a calming liquid solution and bagged twice for transportation back to the house. I will order more from Mark soon for my aquaponic system.

Unexpected These Days!

I will start by saying, I do not give testimonials unless service is outstanding.

That said, Mark went above and beyond to make sure I received my marmorkrebs. Constant emails back and forth — I swear he was constantly watching for mail from me and responded within minutes. My crays needed to be shipped to Florida. Mark overnighted the shipment and I got them before noon, all healthy and larger than expected. Mark will do whatever it takes for his customers.

Satisfaction Guaranteed

I met with Mark this morning to purchase a few crayfish. He was very knowledgeable and took the time to explain in detail how to care for them. He was very approachable and I couldn't have asked for a better experience. Thanks again Mark, I will definitely send any interested folks your way!

Very Happy

I met with Mark today for a local pickup for crays. He was very friendly and punctual. He even gave me a green tote bag to take my new friends to the office — this was beyond thoughtful of him. He made sure to go over the history of this rare cray, and answered every question I had with full confidence. He's so easy going, it was like we'd met before. I highly recommend Mark! If you're a beginner, he'll get you on the right track to successful colonies. FYI, I had a bonus baby! Thanks Mark, you're awesome!

Red Cherry Shrimp

It was a pleasure to meet Mark in person for picking up some email-ordered shrimp. Mark was punctual and helpful with info. Will contact Mark for more if all goes well. Thanks.

I bought a bag of cherry shrimp from Mark yesterday. They look great in my tank — a nice dark red, and very healthy. Mark was very pleasant to deal with, and he even put some extra shrimp in my bag. I could not have asked for a better transaction.

I needed a few marbled crayfish for an international collaborative research project and came across Mark's website. Mark was very helpful and patient, probably understanding that universities act slowly. When we were finally ready to order, Mark helped me make the right decisions regarding the type of shipment. The crayfish arrived in excellent condition, which was perfect for our research. We now know we have a reliable source for our needs in the future.

Bought 20 red cherry shrimp last week. Mark met me in person, even after waiting 30 minutes because I got held up in traffic. The shrimp all made it to my tank safe and sound. Turned out to be a lot more than 20 shrimp in the bag. Good seller, good product, and good prices.

Outstanding

I have a great story to share about Mark and his crays. I was brand new to breeding crays and shrimp, and found Mark's site. I emailed him back and forth for a few weeks, and Mark answered all my questions with professional knowledge and patience. He packed and labeled the shipment with great care, but sadly the USPS destroyed the box, and there were no survivors.

Mark handled the situation in a timely manner, and got me a second shipment a week later. I now have 4 awesome crayfish, and one is expecting. If you are looking to acquire these amazing creatures, look no further — especially if you're a beginner!
