I will be setting up a 180G tank shortly (72x24x24) or one of Marinelands new Marine 36" deep (front to back) and wanted to get some ideas on a tanganyikan community that would remain true to their natural surroundings. I have 6 VERY NICE pices of rock that avarage about 35-40 lbs each. Rock is loaded with holes and crevices (sandstone in tone). I'm not decided on substrate as of yet. I have a small fishroom (14 tanks) and keep pretty much what everyoune else does; large variety of Lamp. compressiceps, Calvus, Nigriventris, Cylindricus, Helianthus, Hecqui, Tretocephalus, Kendalli (large group), Kapampa Fronts, Brevis (Katabe), Lamp. Lemairii, Lamp. Mimicus, Midnight Dickfieldi's, many Synodontis Multipunctatus, Leleupi (bright yellow) Altofasciatus (Kipilli), Buescheri (Zaire Gold) looking for a male by the way!, Calliptuerus and so on. So what do you guys think, would you paint the back of tank black or go another direction?
