DeadStang Posted January 24 Share Posted January 24 I am doing a fish shuffle and will soon have a cycled tank (I will be switching literally everything from a 40 breeder into this new big 75 gallon tank, including as much of the water as I can). I just finished a mini test, going from a 20 long into a 29 gallon tank. It took about 2 hours and so far, all water parameters are stable and the fish are begging and eating, exploring, and doing well. [OK, there are only 2 fish for the time being to make sure the tank stays stable before I start adding fish in from a second 20 tall I have to combine them and free up space...things may go south, but so far, so good.] I read here that it's important to match fish to your water and I have found that personally with houseplants, too. I cannot grow a jade plant for the life of me, but my philodendrons, spiders, wandering Jews, and pathos are insane -- so I have lots of different colors of the same plants. So, on point: I'm on a well with nitrates from the tap at 40ppm and a moderate amount of GH and KH. The pH of the water from the tap is under 7, but it off-gases (CO2???/something) and sits stable at about 8-8.4 in my tanks after it sits overnight and remains unchanged. So I have a busy, "planted" tank (none in the bottom substrate) with lots of things to hide in (rocks, rock piles, and structures), full of anubias of different types, moss, and lots of java ferns (I have figured out what likes my water and at least will not melt -- if not actually grow). I have a wave maker to move water for current and aerate, a high pH, hard water, and I keep my tanks set at 77* degrees...why not make the 75 a Mbuna tank as what I read to be their ideal environment seems to match mine? I have googled around and found suggestions of 20 fish total, all of approximately the same size-ish. It's recommended to get 4 or 5 species, either 1 male to 3-4 females per group to make up the 20. And to try to get fish as dissimilar in coloration as possible (if possible). My questions are: *Which species of Mbuna would you mix in the mini-harems and why? *Would you do 4 or 5 different species? *Would you strive to add them as much all at once as possible...? I can see doing that from a territorial standpoint, but going from 5 fish in an established 40 gallon breeder into a 75 makes me worry that I'll crash the tank as my biofilter with be unprepared from such an influx all at once, although, due to various bumps in the road since I started fish keeping, I can do a 50% water change very efficiently these days, sigh. I just would rather not have to be so aggressive with my water once the fish are in if it can be avoided. Thoughts? Ideas? Too crazy for me to try...? Thanks!
