Nobody is safe with them

Always stinks to lose a fish, but a loss like this should be expected. Pygos should only be kept with Pygos and even then you aren't always safe........

Yup they can take a pleco out (or eachother) at any givin time.

What i did was bought my 8 redbellies when they were only an inch long.. and put em in with a 8inch pleco.

So the Pleco stayed bigger than them and was a constant in the tank since they were babies.

2yrs later I've had 0 problems
The pleco is now 11inches n pygos range from 6-9inches.

Maybe something to try next go round.

You should have expected no less rain.
