I have had neon tetras in the past but one had NTD which spread to the other tetras.
Anyways, someone reccomended ember tetras but I have two questions with them, is there such thing as ETD?
And they are smaller right? So wouldn't it be more likely that they will fit in my betta's mouth?
Would cardinal tetras be better? I don't know, but I really want a small schooling fish to put in my new 10 gallon tank!
