No syno has a true suckermouth like, say, a bristlenose does. But some species do have a differently shaped mouth depending on their enviroment and eating ahbits in the wild. The Clarias, for instance has a much smaller slightly protrusive mouth with no noticeable teeth whereas the Eupterus has a wider mouth with obvious lower teeth. The Clarias has a more vegetarian based diet whereas the Eupterus prefers a more meaty diet. All Synos vary somewhat species to species. It's why I love the synos so much, as it applies to their individual characters and mannerisms.
P.
P.S:I've yet to find a single species of syno that likes it's own comapny. Even my Angelicus likes the company of other synos. Has to suffice with doras tho as he tends to be a little o.t.t for the others to put up with for long.
Also true. My first male Gourami cornered four juvenile synos and kept them there without hesitation. I had to remove them to another tank, but not everyone has that option, so not worth the risk. My B.N male, though, is toughnut. Not even the Gouramies will mess with him. He's been known to attack them if they impose on his doorstep.
