I started with a 8 Gallon Biocube which probably would of been fine for my Mantis but she looked like she needed more room and I have enjoyed watching her more then anything else so I went a little nuts. I will not transfer her into this tank until I am sure water parameters stay good. Let me know your thoughts - Good and Bad Tank: TruVu Acrylic Aquarium - 30x10x14 Notes: Great company to work with, I had excellent communication and they customized the openings to my specifications at no additional charge. My filter / skimmer fit perfect. Filtration: Emperor 280 Rio Nano Skimmer LR: 44 Lbs Fiji LR / 10lbs of LS - Once I transfer Mantis into tank there will be close 55 lbs of LR. Notes: While I wish I could run a sump it is just not possible in the current location (also the only location I could get approval from my wife). I like the Emperor 280 as it pulls a lot of water and the second chamber I use for nitrate sponge. The Rio will soon be upgraded to a CPR Aeroforce skimmer. Heater: Fluval 100 Watt Notes: I love these heaters, easy to set and the alarm feature is great for catching your attention. They are also protected with a plastic cover (nice for when you have a curious Mantis like mine). Lighting: Aquaticlife T5 HO - Originally was Marineland LED ATO: Currently using a JBJ ATO. Simple hookup using a 5 Gallon bucket with Rio Power Head pushing water to tank. This came off my 30 Gallon Biocube that I am upgrading to a Tunze Osmolator. Live Stock: Currently the tank has a CUC that may become food for the Mantis and one Three Striped Damsel. I would also like to place a couple Damsels in the tank. It would be nice to have something to look at when the Mantis is molting. Pictures: New toys before setup Tank with everything in place Tank getting closer. LR / LS and tank water was largely from my 10 Gallon tank I had setup for almost 6 months. I am hoping there is not much of a cycle. Here is the tank with everything in place and CUC / Damsel back in. Notes: I am going to watch tank before I transfer Mantis Shrimp into this tank. I will keep thread updated. Thanks and I look forward to feedback!
