Help With Stocking

[rolo0151]

I've got a fluval Roma 200 that is setup as a community tank. Currently has a fluval u4 & a cheapo all pond solutions 600lh int filter. Ammonia & nitrite at zero, nitrates 5. Ph 7.8.
I've currently got it stocked with.....
x2 guppies
1 Molly
7 neons
4 albino corys
5 zebra loaches
Dwarf gourami
Keyhole cichlid (going to move on as gourami beating on it!)

I'd like a nice focal point type of fish but unsure what to get. Lfs recommend a black ghost knife fish but that is a non starter for obvious reasons.
I have always had great advice of you guys on here so....
What are your thoughts?

Ps I am getting a new filter for Xmas, either aps 2000 or tetratec ex 1200 so filtration won't be an issue

Up your cories to 6. They're much happier in groups of 6+. A good centerpiece fish could be bolivian rams. Really colorful, they're hardy, and pretty tolerant of other fish.

First of all, lower your P.H to 7.0.

First of all, lower your P.H to 7.0.

Is there an explanation or logical reason for doing that?
