Sorry I should have mentioned tank stock with that question; Primarily roseline sharks, rainbow fish (blue and orange varieties), rummy tetras, a couple Juraparis (sp?), and of course a ton of neon tetras; They all seem happy in their current 135 home with 720 gph; I also believe that there is no such thing (within reason) as too much filtration; Thanks for your input, Jeff. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
