Any of you try keeping brook trout? I was interested in keeping one or two because their a nice looking fish and readily available in my area.
Brook Trout are very hard to maintain in aquaria. They need fast flowing, cold water with high DO content. I'd say a 180 gallon could maintain around 3 adult fish if maintained at around 56-58 degrees via a very cold room or a chiller with 2 or 3 very large powerheads for flow and some excellent mechanical filtration to keep the water clean. So, not a good fish for beginners. I plan on trying to growout a few sometime this year in a 33 long with excellent water quality but even so I'm not sure I'll be able to cool the water enough for such an experiment as I theorize they'll start to kick the bucket around 64 degrees or higher.
