Best peaceful tank mates

[steph.j]

Hi , I have a 168 litre tank which currently has 1 bristlenose plec , 6 neon tetras , 1 platy and about 10/12 fry . Any ideas what other fish will be good to go in the tank and how many more I could add ?
Also any ideas what else I could put in my tank or change about it , I’m still not happy with the way it looks - I’ve attached a photo .
thanks in advance

I think your tank looks great!
I would add a black background (something as simple as black posterboard, cut to fit and taped/clipped to the back glass), it would make your fish and plants/deco stand out more...also, I'd move that thermometer to a side glass, near the back of the tank (sorry, pet peeve of mine, hate those things on the front glass, lol)

Do you know the hardness of your water? (pH and GH)

Haha, never even thought of that. Would look better , I’ll move it to the side ?

Hi , ph about 8, maybe just abit less. I’ve just checked on United utilities, I’ve attached picture.
Neons and platy been in there couple of months now and all look good . Added the pleco about 4 weeks ago . Want to add something different but don’t no if the baby fry are taking over ?
