Helloo :)

Can I Put Some Semi Aggressive Fish With Peaceful Fish Without The Peaceful Fish Being Attacked Or Even Killed ?

Thanks :)

In Other Words Is It Likely That A Semi Aggressive Fish Will Attack A Peaceful Fish ?
 
each fish is a law unto its self so its hard to generalise .fish that are classified as nasty usually have the reputation from many keepers of them,having said that i,ve kept fish with peps. and had no problem.quite often these problem if kept in a group behave better than say a single of the species.
hope this is of help
 
it's depends and the fish it may say semi aggressive it don't mean they are I have a mixed tank of both and never have a problem with fish attacking other fish



18 years experience with fish
 
well i have a 20 gallon tank with 18 peaceful fish and 4 semi aggressive fish they don't fight but like all semi aggressive fish is it is being taunted it will attack or it will eat fish that can fit in its mouth which are mostly fry but u should be fine.
 
I had a goldfish that would eat other fish. He was huge and I put little ones in with him and my little ones kept disapearing. I couldn't figure out what the hell was going on until one day I saw a little goldfish in his mouth.

So, I put big fish in the tank with him and he bullied them around for a little while but eventually left them alone.

My point is, it probably will attack or kill your peaceful fish. So, if you care about the peaceful fish I probably wouldn't put them together.

Hope I helped some.
 
All depends on the fish. And, who's classifying them as semi aggressive/peaceful. I've found that pet stores that have those labels are usually not very accurate, think it's more of a disclaimer then anything else.
 
yes there is a good chance that they will depends on what type of fish you are mixing if they are fin nippers or just teratorial.give more info.Have a lok here to see about the fish ya want to mix http://www.thetropicaltank.co.uk/Fishindx/fishindx.htm
 
really, as stupid as it sounds it depends on the fish
i have had "peaceful" fish attack other peaceful fish, or even semi-agressive fish.
i had an agressive fish in my fish tank, and it never bothered any fish. then i got a new fish and it killed it. then when it died i got another agressive fish and it was killed by another one.
they are semi-agressive, because sometimes they can be, or have the tendency to be.
