The Black Long Spine Urchin is a great addition to any aquarium for multiple reasons. These urchins will help control algae growth, especially for aquariums with aggressive fish. Some fish have adapted to swimming and living between the long spines for protection. You can add the Long Spine Urchin to an aquarium with cultured Banggai Cardinal and watch as a symbiotic relationship is revealed in the aquarium. Use caution when handling urchins because they are venomous, which causes painful swelling and itching. They have a very unique way of moving around the aquarium by using a water vascular system. There are water canals through the inside of the urchin that pump water through the madreporite (red eye), which allows their small tube feet to move around the aquarium. Supplement their diet once and a while with dried seaweed.

ACCLIMATION: Avoid exposing new aquatic life to bright lights after opening the box. Turn off aquarium lights prior to floating aquatic life. Allow the sealed bag with your new fish to float in your aquarium for at least 15 minutes (but no longer than one hour) to ensure the water in the bag matches the temperature in your aquarium. A bacteria booster addition can assist with the addition of new aquatic life. Petco offers free water testing in store to determine if your water is safe for the addition of new aquatic life. DIET: A well-balanced diet consists of a variety of flakes, pellets, freeze-dried and frozen foods, depending on the species. FEEDING: Feed sparingly and no more than fish can eat in 1-2 minutes. Overfeeding can quickly foul the water, especially in smaller aquariums.

Orders are subject to verification of payment information by phone or email. We ship for arrival to the customer Tuesday through Friday and Saturday for an extra charge where available.

I have bought an odessa barb about a month ago. About 2 weeks ago she started to form a sandlike, white "bump". I then treated the tank for ich, but now my barb has three areas where its red under the white thing. The white bump is more like flesh, i think. Help?..
Few lumps n black heads
Hi I’m a new owner of two baby red eared slider turtles one is about 1 1/2 inches and the other is 2 inches. Their shells are slightly soft towards their tail and their bellies are also slightly soft I don’t know if it’s because they’re still so small or not. The 2 inch one has these spots on its shell and I can’t tell if it’s shell rot and also fear that it’s shell may be pyramiding.
Hello there, I see some small bumps on my turtle's carapace. Don't know if its shell pyramiding. Please reply as soon as possible (photos provided) Thank you
There’s something in my fish tank, but I have no idea what it is and I need help identifying it. Thank you!
Only a week ago I transferred my two red eared sliders to a preformed pond enclosure, cleaned the filter, added common goldfish from the pet store to the water -- Not adding the water they came in into the pond obviously. I noticed both had a dull white smudge/blotch on their plastron and tiny white hard bumps on their carapace, and I can't manage to pick them off. No dents or bad smells, clear eyes, clean water. Same diet besides one night of goldfish binging. Could they be calcium deposits?
Hi, I bought 6 platy fish and a black corydora catfish about 2 weeks ago, all seem in good health bright colours and swimming round as normal they are in a 48l tank which the pet store said was a big enough tank for them all, but one of them seems to be loosing his scales or I’m afraid he may have itch but it dosent look like it I hope you can help,thanks.
Why does my marigold platy have black spots on its body
My Rabbit has a firm black nail like structure on hoe back, feels attatched to the skin, almost feels like a little twig
My Red ear Slider's shell is feeling a bit soft around the edges. If it touch it, it bends slightly. It this a sign of MBD? My turtle is still young. He's only around 2.5 inches
I just got a three month old baby sulcata and he seems to have 3 small sores or lesions on his plastron. he's in a 40 gal tank with orchid bark. temps are 75-90 (gradient) and I soak him once a day. He has a UV light and is also getting calcium as every meal. I am overwhelmed with the abundance of misinformation I am finding on sulcata care. He eats dark leafy greens at the moment along with some grasses. He's not lethargic at all. Any ideas?
Hi, my tortoise (small one) has black dots since I bought it and today, I noticed the black dots are expanding. He didn't eat anything himself except when I fed him with a stick. He also didn't move and sleep for 23 hours a day. What should i do?
