I've shut down various tanks and have the following available:
River rock (sizes range from baseball sized to softball sized) - 330# available; $100 for all
Limestone (a few large boulders - basketball size) - 60# available; $30 for all
Zebra rock (sizes vary from softball sized to football sized) - 200# available; $75 for all
Misc tub of sand stone, about 15 stones - $25 for all
Rift Lake African Cichlid Substrate Blend 65# available; $35 for all
All of the above come in plastic tubs that you can take with you. Make me any reasonable offer! I hope to take these proceeds and purchase some more Tanganyikan specimens from other forum posts on here! Thanks for looking.
