Could I....?

[Sammy1911]

.... add more corys and ottos to my existing tank?

Currently I have a 65 US G planted with sand tank running an Eheim 600 Classic external filter

8 pearl danios
6 glowlight tetra
1 sae
5 juvie gymogeophagus australis
2 nerite snails
6 mts
3 bronze corys
2 ottos

As far as I can tell I am pretty much at full stocking capacity but since changing my filtration to the eheim Im now wondering whether I could increase my corys/ottos as I know they will be much happier in bigger groups. I would be happy to rehome the tetras but don't fancy scooping them out with the plants... could get a bit messy which makes me think I should just leave them in there.

What would you do?

..Oh and I have 2 bn plecs!

Yes, You can. You really want 6 corys as they love groups. Pretty sure you can add a few more ottos too.

I agree. It's a big enough tank and cory love a group.

stocking only depends on how well the tank is maintained, you are nowhere close to the max if you maintain the tank well

I can't agree with that Fish Crazy. It depends on a lot more than that. One can have a perfectly maintained 6 gallon tank with 5 clown loaches and that is certainly overstocked. So say it "only" depends on one factor is an over simplification.

I know people will get tired of seeing this but...here's my stocking guide.

1. max fish size
2. temperament
3. type of food
4. quantity of food
5. metabolism
6. fish compatibility
7. coral compatibility
8. invert compatibility
9. substrate requirements
10. swimming requirements
11. swimming ability
12. flow requirements
13. sensitivity to changes in parameters
14. sensitivity to water quality issues
15. sleeping habits
16. rock work requirements
17. lighting preference
18. body shape (deep keeled vs shallow)
19. territorial requirements (I can only keep 1 male clown goby in my 210 gallon tank and that fish is tiny).
20. escape and jumping potential
21. temperature requirements (temperate vs tropical also temp range and how temp affects metabolism)
22. growth rate

I think all of this goes into stocking. A well maintained tank is one part of that, an important part, but not the end all to good husbandry.

Well, you can add ottos if they are accepting human made fish food and veggies otherwise adding more will just make them compete for the same amount of algae and they are known to die from starvation. I've never seen my ottos eat anything I put in the tank.
Your filter is only rated 1000L/H with a small 6L capacity so you certainly are not overfiltered and you need to be careful but as suggested 2-3 corys and a couple of ottos won't do much damage though I can guarantee you the ottos can poop a lot, same as a pleco that size.
