I'm using a shallow clear plastic tote for the spawning tank. I haven't moved them to the 20 gallon yet, so there's no room to add water. As for finding ways not to disturb them, I haven't found the best options yet. But I figure that if any die due to stress they were probably not too strong in the first place. I only found 3 today, and the 85 from yesterday was partially fungus but mostly Kio eating them. He's made SO MANY movements already. I believe he ate most. I think cleaning the tank is helping more than it's hurting because I do 2 water changes a day, one larger one in the morning and partial one in the evening.
I bring up the temperature to the tank temp every time I change water. I check with a digital aquarium thermometer and a infrared thermometer to make sure it's as close as it can be.
But since you bring up the drip method, who exactly do you do it? I can only think the water container has to be higher than the tank... I don't know if there's a place for me to do that.
And Thanks lilnaugrim!!! :)
