it all depends what fish you like,first decide what fish you want then get the right sized tank for them
but i do agree with kitty you have so many more options with BIG tanks
Yup Yup I agree with both of you (kitty and cane)! I'm starting a 55gallon community myself I've got it cycling right now with Mature media that was used in the same tank for about a year (I kept american cichlids before) and about 1/4 of the water for more bacteria... and I still doesed the tank for extra not long untill I can add fishys now
