Bettas and gourami together are (usually) not the best idea.would a betta live in community with gouramis, otos and loaches... and poss mollies or platies... i keep getting slightly mixed up views on which fish they can live with.. i just know to avoid other bettas and tetras!
Honestly, a 125L tank with gourami, barbs, otos, and loaches is getting close to full assuming you get the barbs, otos and loaches in the numbers they need.
Let me give this a go...
2 pearl or moonlight gourami
6 pentazona barbs
4 otos
5 loaches (of the varieties I mentioned)
thanks for the above...
so.. 27 gallons = 27 inches = about 69cm
2 dwarf gourami would be 11cm (pearls even bigger)
6 barbs = 30 cm
4 otos = 16 cm
5 loaches = 30 cm
total= 87cm..
Have i done the calculations roughtly right. This would indicate that i would be overstocked. or are the estimations i got off of a website incorrect.
Sorry to be a pain about this, i just want to make sure im doing it right first time..
