Yikes- thanks for the alert. I have GF and Freshwater and posted this
request on the wrong one.

I have two tanks which I think should have a little 'headroom' to add a few
more fish. Water parameters are excellent and I test and change water
regularly. I am considering small danios and/or black skirt tetras. One
tank has 3 aeneus(sp) cories, 2 ottos and 3 Buenos Aires tetras. The other
has 2 reg platys and 2 smaller growing mollies. I am salting it at only
about 2 tbsp/20 gal.

Any suggestions on adding danios or tetras to these tanks, both as far as
compatability and the lightly salted water. Also what's the fewest of
each I can add. I have seen suggestions that every fish I have, have more
species mates, but they all seem relatively active, happy and non
aggressive.

I am sure I will also be adding at least one more tank at some point, but
I am still trying to get a sense of how 'dirty' some of these freshwater
fish are. I have read platys are particularly clean and one can probably
fudge on the inch/gal rule with them - but I dont like them that much.
Any other non goldfish particularly clean or dirty? The LFS help told me
if danios and black shirts were the same size they should produce the same
amount of 'waste'. Might be splitting hairs, but this doesnt sound quite
right to me since the black skirt appears to have more 'volume' than the
danios. Wouldn't size of fish also be at least somewhat a consideration
other than just length?

Thanxx for your help!
