Some sponges (like the tiny yellow/white dots that grow randomly in tanks) are a sign of good tank health but often only last a few months, however sponges like this one can last indefinitely if proper water conditions are maintained.
And yes it is the one that used to be near the Swansea Mall. They relocated further up RT.6 in Somerset in the Autozone Plaza a little before Stop&Shop on the right (if you're coming from the Swansea area.)
MODs, not trying to get in trouble name-dropping a LFS that is not a sponsor of BRS so if this is against forum rules feel free to remove the LFS's name from this thread and people can instead PM me for the name. Not sure if promoting a non-sponsor store is allowed.
