The Blind Cave Tetra, also known as Mexican Tetras and Astyanax Mexicanus, is a freshwater fish that makes great aquatic companions. They’re native to southern Texas as well as the eastern and central parts of Somalia and Mexico. The tranquil fish resides in dark underground caves that have minimal lighting. There is also a variant that stays in mid-level water and enjoys swimming through rocky pools and stagnant rivers and creeks. Although both Tetras make fantastic pets, the Blind Cave Tetra is the preferred fish for aquarium owners.
The blind cave fish only reaches a maximum length of 4.7 inches (12 cm) and sports pinkish-white scales due to albinism (lacking pigmentation). Most Blind Cave Tetra owners use dimly lit aquariums with caves and rocks scattered around the bottom of the tank. They are easy to take care of, making them relatively popular among aquarium enthusiasts of all skill levels. Many aquarium experts recommend a 30-gallon tank or larger with a filter that has four to five times the volume of the aquarium.
Although Blind Cave Tetras are generally peaceful, it’s best to avoid grouping them with other fish outside their species. They tend to nip at tankmates during feeding due to their blind nature and unique searching techniques. However, Blind Cave Tetras do enjoy companionship. Most owners buy at least four Blind Cave Fish so they can enjoy each other’s company. Although buying multiple Blind Cave Fish isn’t always necessary, they tend to live happier lives when they have a school to socialize with.
Captive Blind Cave Tetras are omnivorous and eat a steady diet of dried fish feed and meat-based pellets. Blind Cave Tetras feed on various insects, annelids, and crustaceans dwelling in the underwater caverns and caves, so many Blind Cave Tetra owners toss them a few small shrimp and bugs to munch on during special occasions.
Are Blind Cave Tetras Blind?
As the name implies, Blind Cave Tetras are indeed blind. Although adults don’t appear to have any eyes at all, newborns have eyes that slowly absorb into their bodies as they get older.
Do Blind Cave Tetras Need Light?
Since Blind Cave Tetras reside in dark underground caverns and caves, dimly lit aquariums and fish tanks suit them best. Some people prefer using blue or red lights instead of traditional light tubes

"The fish I received do not look like the fish in thepicture. Why is this?"
- We typically take photographs of one or two fish when we initially get them in. Since we have a large quantity of most of the various species of fish, it would be understandably impossible to provide a picture ofevery individual fish with a specific species. For some of our more rare orlarger fish, the picture listed may be the actual fish that you are receiving.If this is the case, it will be designated by ?WYSIWYG?, meaning ?what you see,is what you get?.
"What happens if my fish arrive dead?"
- While this is a rare occurrence, it can and willhappen from time to time. Fish are live animals and we cannot ensure that everyone will arrive alive or remain alive.We do ask that if your fisharrives dead (DOA), submit a picture of the deceased fish that is in the bag.We will work quickly with you to resolve the problem. We will offer replacement fish for any losses, but do not offer refunds at this time.

We will again, do everything in our power to resolvethe issue and ensure that you have a great experience with these fish.
"What if I'm not home when the fish arrive?"
- We will always provide you with a tracking number. While the fish are packaged to survive about 72+ hours within the shipping containers, we do ask that you make arrangements to arrive home to inspect your fish as soon as possible after they are delivered to your home. Itis always suggested to provide an area for the delivery person to place the boxthat is out of direct sunlight or extreme temperatures.
"What do I do with my fish once I've unpacked them?"
- Like you would with any new fish, let the entire bag float in your tank for 15-30 minutes. This allows the temperature withinthe bag to adjust to the same as your tank and will reduce temperature shock onthe fish. After this time, you can add all of the fish and water that is in thebag into your tank. The products used within the water for shipping will notharm any existing fish within your tank and actually makes the transition foryour new fish a bit easier. After this, expect your new fish to take a few daysto become fully adjusted, this includes hiding, floating at the top, sinking tothe bottom, and not eating. After a few days, your new fish should be acting aswimming like they normally would. At this point, enjoy your aquarium!
"I want to return my new fish because x,y,z?"
- Unfortunately, we are unable to accept returns.We do recommend contacting us via email with yourorder number and as much information as possible. We will try to assist you inresolving whatever the issue may be.
