Oscars get scared, size of tank

Question
QUESTION: Hey i have 2 small oscars like 3.5 In but I've had them for like 2 months now
and everytime I clean their tank they get really scared and i don't know why, i
thought it was going to be normal at first and that afterwards they would get
used to it but that never happened is there something i can do so they don't
get all stressed? I know my tank is really small for them i plan to upgrade it
soon but how much time can i keep them in that tank ? i don't wanna stunt
their growth.

ANSWER: Hi Guillermo,
 You didn't tell me how large/small the tank was -- that is key information to answering your question. So how small is it?

QUESTION: yeah sorry its a 25 gal

Answer
Hi Guillermo,
 25 gallons is not going to be large enough for much longer.  An adult oscar is 12 to 16 inches long and they can reach that size in a little over a year if kept properly.  
You  should be looking at something in the 75 gallons or larger size to keep these fish happy and healthy.
