Would this be overstocking?
 

So I was wanting to change my tropical tank around a bit with new fish etc. I was wondering if I could keep:
Zebra danios x 12
Large angelfish x 5
Small Pleco x 1
The fish would be kept in a 240litre (63 gallon) tank. I know there shouldn't be much aggression but would it be fine to keep this many fish in this size tank? Thanks guys

The tank has room [except maybe the pleco, see below], but I would not mix angels with danio. Angelfish are slow, sedate fish that love to cruise slowly among branches, plants, etc., whereas there danio are fast swimmers. The angels will most likely be intimidated by the danio. There is also the possibility that danio will nip the angel's long fins; the temptation is too great for a lively, boisterous fish like any of the danio species.

If the pleco is a common pleco, it gets more than a foot in length and needs much larger quarters. But one of the smaller species, such as the Bristlenose Pleco or an Hypancistrus species would be fine, they max out at 4-5 inches. Or there are the interesting Whiptail Catfish in Rineloricaria.

We have fish profiles, second tab from the left in the blue bar across the top, and info on suitable tankmates for most species are included. Have a look at the angelfish profile, Pterophyllum scalare, you can click on the shaded name to go directly to that profile.

Byron.

Yes I was hoping that the danios would mainly stay at the top and school with each other because there would be 12 of them while the angelfish stayed towards the mid section and I thought they might have some confidence considering their huge size compared to zebra danios.
I should have been more specific with the Pleco, it is just a little bristlenose.
Do you have any suggestions for larger fish that I could keep with 12 danios? Maybe electric yellows? That would be a big help thanks.
Thanks for the help with the fish profiles, I'll have a look

Replace the danios with some fully-grown cardinals or black neons and you should be fine.

I love bristlenose plecos..

Electric yellows are a bit too agressive... Byron may be able to think of something though. Maybe some of the more peaceful cichlids though...

Problem is I've already got danios hahah.. Thanks for your answer though :)

You have lots to choose from--except any slow, sedate fish, and nothing aggressive.

First, other shoaling fish work well, and with active danio some species in the larger rasbora, medium barbs [the Black Ruby Barb is stunning in a group], other danio; check through the species under Cyprinids in the profiles.

Bottom fish along with the BN could be the smaller/medium loach species as you have room for a group (5-6 minimum), Botia kubotai, Botia striata, Botia histrionica...there are several, these max out at 4-5 inches. Several are in our profiles.

For "larger" mid-water, the Bolivian Ram among cichlids, or some of the Central American medium species. Then there are the rainbowfish, in our profiles under the Athernids.

Thanks, I'll defiantly have a read of all these fish and then hopefully come up with a good bunch of fish. Thanks again
