Incompatable tankmates that will never work. But do anyway (?).

  • We are currently upgrading MFK. thanks! -neo
I had 5 male bettas in a heavily planted 20 long for over a year with no deaths. They did fight occasionally but i guess there were so many plants that they had plenty of room to retreat to and hide. It was kind of an experiment to see if it would work.
 
In another tank i had a 18 inch needle nose gar and a feeder guppy last 3 months together. The gar would eat feeder goldfish but had no interest in the guppy.
 
Yeah, that's a lot of potential aggression in that tank. I do know that sometimes crowding the tank with cichlids will help (it seems to be a popular method with African cichlid keepers, anyway). Have your jags bred?
 
5 (3 different species of Leiarius) Leiarius' in a 300 gallon stock tank, they nap together in a catfish pile, it's awesome.
 
right now i have all juvies 3.5 - 5.5"

loiselli pair
1 GT
1 jack dempsey
convict pair
1 nicaraguensis
2 carpintis
1 red texas hybrid
1 true texas
1 managuense.

in a 150g long. these are all young fish, i will thin out and keep just the ones i like the most. hardly any skirmishes break out its mostly just chasing and "bucking" at one another
 
I have 4 Giant Danios in a tank with a palmas polli, Oscar, 5 filament barbs, and a pair of JD's. They were thrown in a while back to be dithers/eventual food before I got my barbs. The only deaths in their little school were from jumping out lol.
 
Let see, I had one tank a while back that included:
Red Devil
Oscar
2 Convicts
Green Terror
Black and White Skirt Tetra- these two were thrown in by my brother when he wanted to change up his tank and they adapted. I always thought it was very interesting because they basically turned aggressive, and by this I mean they actually chased off the oscar and green terror. It always blew my mind

Another tank, has:
ZZ Flowerhorn
Red Devil
2 Jags
Green Texas
Red Tiger Botia-I think he is the oddball out of this group, had him about 4 years now and he's always maneuvering between cave formations so thats how I think he's safe.

Also one other tank has a Jewel with a Yoyo Loach and they seem to be buddies haha
 
My combo that shouldn't work:
~9.5" female Midas
25 BA Tetras
4 Herotilapia Multispinosa (rainbow cichlid)
Pair of Kribensis
1 Firemouth
8 Clown loaches
3 BN Plecos
1 Vieja Synspilum

Even in breeding mode and guarding eggs she was not as bad as I have read other midas to be that are just going about their normal day.

I have also introduced two 1.5" Uaru A. with a 6" male GT with which he started to guard instead of eat. Was extremely odd but nice to see. Those two Uaru grew up hard and started tag teaming other fish who got in their way or started on one of them.
