Tank mates for the carnivorous pleco...

I have three tanks all with BN in...

Tank 1-Fluval
2xBN + 120 bN FRY + a couple of mollies, 4 guppies, and 2 cory's.....

Tank 2-Clearseal
1xBN (4inch) + 5 BN fry... and one red male betta (picture in the current comp)

Tank 3-Rekord
3xBN (1 clown pleco about 3 inches) (1 BN about 3inches) (1 albino gibi about 4.5 inches)
+ 5 mollies and 3 female betta non of the fish have shown any hostility in the past..

Ok as a treat and after reading your other post about BN tank mates, I decided to add 10 small tetra to a well established
*******tank 3 - Rekord 80-- **********just until I set my fourth tank up.... over the next few weeks

Anyways I did a water change on all tanks Friday before I went away for 2 days.

Returned back Sunday night around 9pm to find 9 of the new small 1inch tetras missing from Tank 3.

Dont laugh..... lol....

Appears that even though I left food in the tank for the two day trip away that one of the fish in Tank 3 seems
to have helped him or her self to a extra lunch of 9 tetras over the last two days.

I am now carefully watching the fish for any signs of territorial dispute or flaring...

what do you guys and gals think... and please refrain from the jokes.....
