First real batch of wigglers...

[jeep]

In at least 40 spawns, today is the second time my discus have produced wigglers. The last week they only had about 15 and today there are about 50+ and still hatching. The long wait is over

Question: When should I start adding tap water for the fry. After they hatch or after they become free swimming?

Thanks,

Brian

You can start after they hatch. Do very small amounts at a time - like 10% or less. Make sure the water flow is directed away from the fry and is gentle. Fry are delicate. Do several small water changes 6 or more hours apart. There is no hurry to bring up hardness. Make the transition easy on the fry.
