Ram Fry/RO Water

[Cathy G]

Hi all,
I have managed to hatch 50-60 blue ram fry. They have been free swimming for a couple of days and I'm feeding infusioria and microworms. I'll start the bbs after the weekend when they will be 1 week old. They are in a 2g tank to keep a higher concentration of food, after 2-3 weeks they will go in a 10g or 20g tank for grow out. (If anyone has suggestions to improve upon my plans, feel free to mention them!) Here is my question.

I hatched these guys in RO with Hydrogen Peroxide. As I am doing water changes, I am still using RO. I do add Kent's RO Right to my mixture so the necessary electrolytes etc are in the water. My question is, is this ok in terms of the fishes development? Should I add any tap water anytime soon? (My tap is VERY hard, with 7.8 pH). I figured I wouldn't until they were good and big/strong. Then add little amounts in the water to start acclimating them to the LFS's water. Is this a good plan?

Thanks for all your help,
Cathy

Your plan seems sensible to me. You probably will be safe adding some tap water after about 4 - 6 weeks. Fortunately I don't have your problem - or tap water.

I don't use RO water so can't help there, but the tank may be a bit small for that many fry. I have about the same # of 2 week olds in a 5g tank and need to move them asap! Getting very full in there. Once they are seeking out food they can be moved to a slightly bigger tank just so it is more stable. Good luck with yours!
