snakeheads
they were 9" and supposedly the more docile species, reputed to be more community than anything else. but mainly, they were 9" and way too small to be noticed by the gars. in fact, it's probably a mark of how docile my cubans are compared to others that they didn't eat them. the smelt i feed them is actually larger than some of their uhm, "temporary" tankmates. i also actually know a few people who keep adult pleurothalma with small fish and also cuban gars, don't think it would have been too bad of a combination. but these were actually in the big tank cause they were killing the small fish inthe growout, i was really resigned to the fact that the gars were gna eat them, so i was really pleasently suprised when that didn't happen.
current pbass
i actually gave this a whole hell of a lot of thought, hard to explain in a few paragraphs. but here goes.
1.pbass are usually much more aggressive and boisterous in packs, i specifically kept a small number to prevent this. i actually test ran it with one pb, it was mostly scared by the gars and never eats as boisterously, in fact the gars have been spooked out tonnes more times by my african arowana then my pbass. when it worked, i went ahead with 2 pbass, which seems to be as timid as 1. the moment i feel the gars are getting freaked by any excessive splashing i'd get rid of the pbass thou...
2. more importantly, cubans are atractostues, and much more able to hold their own. a while back i had a dat and barramundi in for a short while, the cubans were not affected at all but even the 18" florida gars were much more skittish. i really don't think it's so much of the size of the cubans that is responsible for my so far success with keeping this combi but rather more of their aggressive, sturdy nature. in fact while looking for past examples of this combi i found that more reputable guys such as chad over at ap had this combi, and since most gar gurus had not seemed too concerned i wasn't too concerned. so basically imo it's alright to have 1 or 2 smaller pbass with larger atractosteus sp gar as it's far more likely that they're going to pick on the pbass rather than the other way round. with lepisosteus gars however, it's probably a bad idea. they seem to display much more skittish behaviour. but that's just my opinion...i'm probably going to be proven wrong soon
3. why not oscars then, i had one(terrible, stupid mistake) for a day and it terrorised my cubans, and it was barely 15"....perhaps it leaves the smaller fl gars alone as it doesn't see them as a threat to it's territory..lol
