Water paramaters at last spawn.

Hello
I though that I would list the results of my last water test done just after I noticed the new fry. Using a Tetratest kit the results are,
Temp about 29.5 degs C
ph about 7.5
GH about 17
CH about 4
No2 less than 0.3 mg/l
Co2 content shown as low on the graph with the kit.
I think my fish spawned following a good 1/3 water change using half RO and half tap water.
Ten fry seen so far.
I hope this helps someone.
just curious

Hi,
Just curious..
Are the Zebs FO?
Have they ever spawned before?
How old?
Was the water a little cooler for your 1/3 water change?
If so what did the temp get down too and how long was the temperature down for?
Peace

Hi Troy
I don't know what FO means.
My tank has about 15 to18 adult fish in it so I don't know which fish have actually spawned this time but I had three batches of fry in early 2002.
I'm not sure how old the fish are. I have had them at least 5 years and I bought them as adults.
The water went down to about 25 degrees when I did the water change but it heated up to it's normal temp I would guess within two hours. I keep the fish in a Juwel Rio 125 tank / set up with an external Eheim Pro 2 Thermo filter fitted as well so there is quite a bit flow and the thermo heats water quickly when required.

Hi GS
F0 is a term for wild caught fish.
F1s are first generation of tank raised/aquarium bred fish.
F2 are the fry from the F1s and so on.
Im guessing they are all FO.. if you had them 5 years and were already adults when you got them.
So that probabaly makes them at least 8 - 9 years old min
Congrats on the spawns!
Peace

Congratulations!
Troy if you read GS's last response he states that he had fry in 2002 so they could be F1 or F2 fry I believe!
ah i missed that

The current fry are from the same group of adults which produced the 2002 fry. They are not from the 2002 fish breading, so I would suggest that as these fish are are so old they were probably wild caught as suggested.
