I have very hard water in my area.Will rummy nost tetras be ok in this water? The wikipedia article on rummy noses say no more than 9..But as long as ammonia etc are not present they are fine in most tanks, but to breed they MUST have soft water,acidic too. I have a high PH and very high hardness. If i cant keep rummynoses happily what is an alternative (will be going into a community with platies,harlequins,BNs,and others that im researching)
