dear forumers,

i been thinking to put a cichilds in my green terror tank.
the tank size is 4X1.5X1.5
currently there are only 1 green terror with 3 clown loaches..
FYI, the terror is about 6 inches and the clowns are at 2 inches..

is it safe to put one oscar in?.. or can you suggest any cichlid that can get along well with my gt and clowns?

tq
