About how many more can i add?

[poeticpyro]

i have a 6' tank (125 gallon) and it houses the following...
* 9 tiger barbs
* 1 gold-nugget pleco
* 1 snowball pleco
* 1 bristlenose pleco
* 5 clown loaches
* 3 yo-yo loaches
* 2 pearl gouamis
* 1 opaline gourami

i want to know if i can add 1-2 more clown loaches and/or 2 more yo-yos. i also want to know if i should increase the tiger barb school.

filtration is 1 eheim 2217, but i'm already out to buy a second. all fish are small ... everything is under 4" (at the moment)
thanks!

Adding more yoyos would be no problem, and one or two clowns could fit. Just make sure you're adding very healthy fish - AFTER a quarantine period.

Ya get that other 2217 on there one isn't much flow for a big tank like that

thanks.
yeah i ALWAYS QT them... had issues with ich before and i learned the hard way, but at least i learned. so... only two more yo-yos, that's cool. there are baby ones at my lfs for $3. i'm excited and they have been there (no losses) for four weeks.
