I am restocking (ok, planning ahead of restocking) my 33gal community. Tank has 36" x 12" footprint, with PFS substrate. Well planted, with some driftwood. Well filtered with Tidal 55 and AC70 hobs. Current stocking is:- 9 rummy nose, - 2 young but sexually mature 2 GBR (M/F), - 3 otos, - cherry/amano/ghost shrimps. I'm having heater issues right now, can't reliably get over 78.5-79.5F, but I'm targeting 80. I want to add 1 school of sand-sniffers, and am waffling between kuhlis and corys. Which should I choose? If corys I think I'm limited to sterbai or bronze due to temp for rams, right? - Kuhlis might only be seen rarely during the day, will be cheaper to buy (maybe half the price, typically), and might contribute to control of mini ramshorns (not a problem yet, but I'm a perfectionist ). - Corys would be more $ initially, but would be more out and about during the day. I clean and change water weekly (30%) so while I would hope for a tidiness assist from either type, I'm not relying on them. That said, is one more efficient than the other at helping me to keep a clean substrate? How about ease of feeding (ie not dependent on live foods, though I'm happy to add bloodworms and brines now and then)? Thanks folks!!
