need help

i have this love of asian loach tanks...they are fun to watch absolutely hysterical,,easy to keep....and for the most part relatively inexpensive.
if that is a 20 long tank it would be ideal....for a small asian set up...
6-8 kuhli or black loaches, 6-8 dwarf loaches, 4 yoyo's , 4-6 harlequin rasboras, 1 male betta,
run a hob filter that is for a 50 gal tank....and a whisper 40 air pump for a good stream of air bubbles....lots of driftwood,tons/ lots of plants , at least 1/2 tank play sand sub..other half can be tiny river pebbles with smooth edges, well anyway that is my prejudice....if u have never had loaches u r in for a fun time..once they get settled in they are down right comical and u they play all the time....couple of marimo balls for them to lounge on...or if you sqeeze the water out fo the balls each morning...the marimo balls float and the loaches at times will play with them like they are beach balls...

You might think about getting a bigger tank for those baby convicts- they like room when they get big!

For shellies I would recommend n. mulifasciatus and brevis. Those are about the only two I would try in a 10 gallon. For a larger tank, julidochromis work well with other shellies.

tiny goldies, (pearscales are cute!!! ) mollies, guppies, pea puffers, or an african frog
