Ideas planted 20 long

[Annie]

Hello everyone!  I just wanted some insight or recommendations for my planted 20 long. My situation is I’ve lost a few fish in the past weeks. My dwarf gourami, corys, the last of the glass fish, a couple tetras, and my pleco. (wasn’t all at once) Pleco was after a water change. 
I was already battling with Algae before my Pleco died. I tested my water and it was good🤔 I got 6 tiny otocinclus two days ago and they’re still doing good. 
As of today my water test indicates-

PH 7.6

AMMONIA 0

NITRITE 0

NITRATE 20-25

                        The fish in there now are :

1 cory

6 tiny otos

3 von rio tetras

4 silver tip tetras

Heater is set at 79  degrees 

I have also battled with the ick and have bought aquarium salt to add during water changes. 
instruggle with siphon vacuuming. And i bought FluvalSmart auto gravel vac and had problems with…and snails!

sooooo. Some of my thinking is what else can I fit in there that helps with clean up and is beautiful.

considering a beta?  Or another dwarf gourami .  I also really like the look of appistogrammas but not enough room for a school. More Cory’s so he’s not lonley and they’re adorable, 

hillside loach I wanted to replace the pleco but I read they’re not easy.

‘what should i dooooooo?

Thanks , Annie

i would suggest, since you have been losing fish the last few weeks, give it a few weeks to a month before getting more fish. if the otto's do good for a few weeks, then id think your tank isnt sick.

I agree with lefty, give it time to make sure all the fish are healthy and doing well

Thanks for the response.

I will wail it out to make sure. But when it is the right time what did y’all think of my fish ideas?
