as long as your post pertains to the original thread title, there is no such thing as hijacking*S* i got my question answered*S* and if theres alot of folks readin and you have one that pretains, be my guest*S*
Honestly I wouldn't suggest a breeding pair in a 20 long. It will be fine for now but give it time and eventually they will need a bigger tank, one will be too aggressive for the other.
And a 10 gallon is no way big enough for a breeding pair. Again, its fine now but expect a dead con soon.
a ten would be fine if u put them in there to breed and then move them back to a larger tank, i use a 20 long but still do the same thing, except they go back to seperate tanks (don't need and fry in my other tanks)
