Just because we (humans) think a tank is big enough

[duanes]

doesn't mean the fish, or others do.
Sunday I was given a bucket of fish, and some crustaceans, and they were put in my 180 gal,6ft tank.


None of the fish are larger than 6", same with the largest inverts.
Even the smallest shrimp are @ the average size of the fish.

This morning I noticed a bit of a ruckus, and with a closer look, the cichlids were tearing up a 4" shrimp.
I don't believe the cichlids are large enough to kill the shrimp on their own, but I'm guessing over night, the larger invert probably did, and the cichlids just cleaned up the site.

I agree. I'm a fan of low stock as well.

I was wondering how long those were going to last in your tank.

Cichlids would kill it without a doubt. Antenna and legs are nipable and once they realize this wiggly thing that can’t defend itself is delicious, it’s only a matter of time. Watch out the the larger inverts don’t snatch the smaller fish too.

6" cichlid beats shrimp every time.

Nom Nom Nom!

It also appears that the largest Andinoacara has decided the 180 is not large enough for he, and the other similar size male (both topping off around (or just under) 5.)
