hi supasi
theres usually a few tanks at wetpets in palmy with geo suris
i have my 2 over riversand
ive read that while they are young stocking levels are of no concern but when bigger the males get teritorial and when breeding they peotect their nests quite well
they are gentle fish so avoid too many lage agressives
aparently they also take 1.5 years to reach breeding maturity
the best thing i think to do would be do a google search on the species your interested in and make the judgement yourself cos you are the one looking at your tank
and as for plants i reckon if you put yurplants in pots or had them planted behind i log or something they probably wouldnt get to the roots
ive noticed they dont like being in confined spaces
ive read that sand and fine gravel are best for them cos large sharp peices of gravel/stone can cause damage to their gills and mouths they look cooler with sand too cos it comes out their gills
one othe point their messy eaters so good filtration is a must
hope this helps you
chris
