Community tank set up

[Bagstar]

I am very new to fish keeping and have finally managed to find somewhere to keep my pleco safe and well on display in a pet store. Now he has gone I have purchased a few fish but would like to know what or if I can buy more?

I have a 155 litre tank or 40 U.S gallons with:
5 Neons
5 Rainbows
4 Guppys
5 Danios
1 Clown Loach
1 Gourami

Im hoping to give the Loach away soon as well. The tank seem's very empty at times.

Keep the Clown Loach and get a few more. They're very fun. But if you really want to get rid of the Clown Loach, you could get 7 more Neons, 7 more Danios, and get a few Otocinclus Catfish...like 5.
