Adding smaller pbass with bigger ones question

[Lockheed]

I'm currently growing out 2 baby pbass (3.5 inch and a 4 incher ocell/mono farmies) with 3 similar sized tinfoils in a 40 gal. My local lfs just brought in some baby orinocos which i've been looking for for some time. The problem now is that the baby orinocos are quite small, about 2-2.5 inch. If I add 1 or 2 of these orinos with my pbass, will they get eaten?

I'm also thinking of DIYing a divider or a large breeder box, which seems to be my safest option.

Let me know what you guys think. Thanks!!

Sizes are kinda close but the 4 inchers scare me... if you could do a divider that would be great. Pbass often times eat whatever can fit in their mouths.

Put them the new ones in a quarantine tank and grow them out until they are closer in size. It’s a good idea to qt all new fish Anyway so you don’t run the risk of introducing any parasites to you current stock.
