I avoid conditioners that are breed specific. I don't like them.
I use Prime by Seachem in all my tanks including spawn tanks and grow outs. I love this stuff because, as mentioned, it is inexpensive considering how long it lasts you. I bought a small bottle of it several months ago and still am using the same bottle despite my many tanks!
Also, I don't add anything else, especially not AQ on a regular basis. I do sometimes add stress coat.
If my little finned babies seem to be stressing over something or have eaten tail (I have a couple HMs that do this) I add Indian Almond Leaves to their tanks.
