Will a baby electric blue jack dempsey go with a baby albino oscar, and plecostomus in a 30 gallon tank?

Question

I'm only keeping those guys in their for a month because i am renovating my 500 gallon tank but would those guys be able to stay in there for about a month then switch to 500 gallon with 2 green terrors and 1 albino oscar and 1 jack dempsey. also how large should the pleco be when with the oscar and jack dempsey?

Answer 1

Yes, as long as they are small they will be fine. I have a Jack Dempsey and an Oscar with a Pleco in a 30 gal tank. The pleco can be any size from small to big since they will not try to hurt other fish. I do not know of green terrors. It is best to introduce all fish in a tank at once with the Oscars  because they are a little territorial and may try to harm littler fish.
