Oh.. my god! I should advice Sahari on how to keep this fish... is my mistake. Ok, here my advice to you guys. As what I experienced b4, Lee farms guppy lived in pH5.5 ~ pH6.0 water condition and he fed them with live foods.. Ok, you guys cannot direct introduce this fish to your new water, you need to keep them in their original water mixed with new water, ratio is 8:2 for the 1st day, 2nd day, remove 30% water and add in new water and original water in 50/50 basis. 3rd day as 2nd day.. and following day, if the fish ok, check pH rate (now should be around pH7), time to introduce them to your new water! By the way, you will lose some of them during this period, I can't help..
