[APD] Re: Aquatic-Plants Digest, Vol 12, Issue 25

Oops! Forgot to mention the substrate! 2-3" of soil mixed with vermiculite capped with 1-2" of 2-5mm gravel. The foreground (unplanted) gets vaccumed regularly, but the backs a different story.

I've heard all about the wonders of loaches. But don't they get big (for bottom dwellers)? Shouldn't they be kept in schools? Isn't my tank stocked heavily enough with fish already? Don't really want to add anymore fish to this tank if I don't have to. Especially big fellas.

My attitude towards the snails does change with my mood too! They used to be fine, but since adding the discus ~5months ago, the population has exploded due to extra feeding. When I'm sitting back on the couch watching the tank they don't really bother me, but when I get up real close and see the "gravel" moving and the thousands of snails everywere, they tend to give me the irrates. 

If copper aint going to work/is too risky then I'll give it a miss. Back to manual removal I guess.
