Hi I'm christy and I have a newly setup 50g and an established 30g. I stumbled on this site when looking for info on butterfly fish, I have mostly convicts and a few dempseys, which as soon as is cycled will be moving to the 50g. I found this a few days ago and have been reading ever since! So glad there is a place other than petsmart to get advice from. There aren't many stores around here anymore that aren't chain stores, and can actually give you advice because they have experience.
