Swimfins
This is as good as it gets.
LOL! This is something I didn't know thanks for the info.
I find them intriguing. My tank is on a sideboard in the kitchen and while I do dishes I watch them, they are something like housecats (am I nuts?) I have two and sometimes I see them rubbing against the smooth pebbles something like a cat does against your leg if ya know what I mean. I'm buying two more cories tomorrow. And maybe another sword for my lone male. My water levels today are 0 for amonia and 0 for nitrites wooohooooo off to th fish store I go
Thanks.
