A 20g tank is much to small to house clown loaches. They like to be in groups of at least three, but the more the better. I think at least a 75g tank is recommended for keeping clown loaches as they can get about 12 inches.
well i may very much get some i have a snail problem
will they be compatible with,
3 peppered cories
17 baby neons about the size of a finger nial
a juvinile angle
4 zebra dainios
a pair of guppies
in a mildly planted 20 gal?
you've got that tank packed once all those fish get full grown. are you getting the fish now while you get your 90 set up? i thought i remembered you getting a 90g?
