Your tank is looking great! Is that a pink tailed chalceus in there? Your SD's are getting HUGE. Also, do you have a link to the feeding ring you have?
Thanks Rayne. Yeah, it's a pink tailed chalceus. He and the SD's have blown up over the past few months. I'm surprised how slowly the Oscar is growing...he's the slowest growing O I've ever had.
I made the feeding ring from drip irrigation tubing and some barbed T fittings. I initially used some clear tubing, but I think the black irrigation tubing is less of an eyesore. Tip: the irrigation tubing will kink up if you try to make a small (tight radius) ring. If you are looking to make a smaller "ring", just get 90 degree elbows instead of T fittings and make a square or rectangle. They are easy to make and will probably be cheaper than buying one from a LFS.
