Hi Everyone
Good information Lobo thanks!
Thankyou also FlyingDiamond on your information, yes I did buy the phup and ph down, I have used it when establishing my tanks. I don't have not used it since. My guppy had babies, unfortunatley, my husband felt guilty and took mama out of the nest box, I had put her in about 7pm, I went down and saw that she was hiding in the driftwood, and could see no fish at all, as they were all with her eating her babies as he gave birth. I took her out in mid birth and saved only 3 baby guppies. I told my husband I put her in there for a reason lol..He knew this before, but got drinking and forgot I guess.
More guppy babies to come in a week, and more after that lol.
I do have 5 more tetra's for my 30 gal tank, to keep the biologibal water healthy, as I only have 3 baby guppies in that tank. Lots of fake floating plants for them intertwining from right side of tank from top to bottm, and keep them all well fed. For anyone that don't know, your guppy when giving birth will hide in a chosen spot usually dim area of tank, sit, and swift movements of her middle to tail jerking like she is swatting something away. This is to help her with the birthing canal, to push the fish out. I had my camera ready, but didn't go down to the rec-room until it was all over at 10:30 pm, to which I had been watching her for hours before hand.
Though resting can also be taken for nesting. lol Both my neon tetra/guppy tanks have a temperature of 79F..I now have given up thinking of breeding tetra's. Before I know it, my tank will be over run with guppies, unless I let nature take it's course in time, and stop saving all the babies lol.
Thankyou for your reply Flying Diamond and all!
