:swear: I have seven juvenile gouramis and two juvenile albino chocolate plecos and a couple of snails that rode in on some plants in a 55 gallon tank. I had four guppies, a Betta, and three crabs too. But the two guppies “disappeared” and the other two kept jumping into my filter. So I moved the remaining two guppies into a ten gallon tank to live with another Betta. Then one crab found it’s way into my filter. When I put him back into the tank all the gouramis started biting at him. I moved him into another tank but he died the next day. I found the other two crabs dead on different days with their legs missing. Now the Betta has “disappeared.” I find no bodies floating and no remains on the substrate and I took all the plants and rocks out to trying to find them.

Could the gouramis be eating them? If so, how do I curb this aggression or are guoramis naturally this aggressive towards their tank mates?
 
what kind of gouramis?

they are known to be nippy, but I don't think they're out right killers.

if you want, you can bring them to my place, my wolffish will teach those gouramis a lesson. :D
 
I have 2 Pearl, 2 Brown, and 3 Opaline Gouramis. I had a little difficulty with 1 Opaline gourami picking on all the other gouramis but I took him out of the tank and rearranged things around and that settled him down a bit with just the other gouramis. Now all the gouramis pick on everything except for the plecos. Would it help to take them all out and rearrange the tank when I put a new addition in?

Thanks,

Jacky
 
Guppies are jumpers... And they dry out and get tiny... Check the floor...
 
Yes, guppies are jumpers. They are very good at jumping into filters! Checked everywhere. But that could very well be it and I swept it up without realizing it when cleaning.
 
Your crabs are losing their legs and dying? Do you have a place where they can get out of the water? There are very few fully aquatic crabs. Also, most crabs sold are really brackish and need some salt in their tank. Losing limbs can be a sign of improper enviroment. Of course they could of been fighting with each other, too.

I don't think your gouramis are to blame. Bettas are super jumpers, and as far as not finding the first two guppy bodies, I think your crabs ate them. That's what they do, clean up. If the other guppies jumped then I think you can't find them because those little bodies are so hard to see when they dry up somewere. Do you have a dog or cat? My dog ran off with a killifish once, I think he thought it was some sort of jerky treat!
 
i would think its the gouramis..........i have a blue gourami in with my electric blue jd and it is extremely aggresive......it kills anything even slightly smalller then it in the tank..........so my guess would be the gouramis.........just my two cents..........
 
I went to my local fish store to ask them for some tank mate options for my aggresive gouramis. They told me that they have never heard of gouramis that did this. It is nice to know that I am not the only one to have observed this behavior with these fish.
 
My major disappearing act can be blamed on an internal bacterial infection + small fish. Mine would die and get devoured by tankmates before I could remove them (I was absent for most) and then those that ate them would die and get ravished.

Other than that (which happened fast and caused a massive die-out) my only other disappearer was a jumper.
