Product Description

Red Ball Sponges, Pseudoaxinella lunchearta, are a fairly common sponge from Florida and the Caribbean characterized by their bright red and orange color and ball shape.  In some areas they also grow in flattened fan shapes, and many of the larger sponges have wavy convoluted sides.  They inhabit a fairly wide range of habitats from 10 feet of water to well over a hundred feet of water, and from inshore to offshore zones, so they are tolerant of all kinds of water quality and temperature conditions and are thus well suited for aquarium keeping.

Sponges are filter feeders, primarily feeding on bacteria and dissolved organics, so they can be a little challenging to keep in some reef tanks.  If not fed regularly with some sort of planktonic food, the will slowly starve to death in most reef tanks, so be prepared to feed them on a regular basis.  Most sponges will have a small amount of substrate attached to their bases which can be superglued or epoxied to a rock so they will stay put in your aquarium.  You can als wedge the sponge into a crack in the rock work of your tank, but I would not recommend “planting” them in the sand because the base may end up dying.  Contrary to everything you’ll read about sponges, these sponges can be safely removed from the water and exposed to air for brief periods of time without any lasting damages.  We’ve handled thousands of these sponges over the last 30 years and most have been exposed to the air for brief periods of time without any problems, so don’t make a huge deal about not letting the sponge touch the air while you move it from tank to tank or while you mount it on a rock.

Our target size for the sponges we ship is about >2” to 3.5 inches diameter and about the same height.  The sponges are wrapped in paper towels and submerged in water for shipping and they generally ship real well and will do well in your tank.

Please Note:  Any new fish purchased from us or from a local pet store should to be quarantined.  All fish from anywhere in the wild can be possible carriers of bacteria and protozoa that can lead to an infection in your system, so we always recommend that you use some sort of quarantine system prior to adding them to your system.  If you have a fish only system and can medicate the whole system, you may not need a separate quarantine tank.  If you have a reef system that cannot be medicated, a good ultraviolet sterilization system should prevent any kind of disease outbreak.  We medicate our system for bacterial infections and protozoans, but because we don’’t always hold our fish for long periods of time, there is no way to be sure all the protozoan cysts have been killed.  A little bit of prevention will save you lots of trouble down the line.

    Holy smokes, this thing is big. Took your advice and was able to expose to air for a short time with no ill effects.

    I have had the nano version of this sponge for over 6 months now and it is doing great in my 30 cube. Sponges are notorious for starving to death in the home aquarium, so I was hesitant to try one, but these guys are hardy. My small one has even grown a bit, so that is why I decided to add another full sized red ball sponge. Looks awesome and provides great color in those shaded areas of the tank. Highly recommended.

    Update: This sponge is just ridiculously hardy. I had an incident where I accidentally poisoned my 20g with heavy metals, killing off nearly all the inverts. This sponge was one of the few survivors.

    These are beautiful, quite hardy sponges. Do note that, while their color is indeed bright red and very beautiful, it’s not as fluorescent as in the photo. It’s more of a tomato-red color. Also, I’ve never had any issues when exposing these guys to air. They’re quite hardy and very useful filter feeders.
