Ive got 3, two nano type tanks and a 65 litre tank.
Would eventually like to get it back down to one so i can focus on a heavily planted tank and currently all my fish are incompatable to but all in one larger tank ... but thats just the way it is! Fish are great
Only the one 240l Rio. I have a 178l in my conservatory that i'm supposed to be selling, i really want to get a second on the go but the other halfs not having it!!!
I have a 35G, 30G, 15G & 5G setup at the moment, have a 40G & 35G in storage that I'm hoping to setup in the next few months and I just went and picked up another 35G this morning.
29 running if you count little 2.5's & 5's used for hatching & growout. I just got done setting five 40's on a rack, they aren't running yet, either are the spare 10's & 20's, 63 or 150.
I have a 10g shellie, a 20g RES (turtle), a 29g marine, a 6g blue crayfish, and a 29g (soon to be 55!) cichlid tank.
I also have an outdoor goldfish pond.
