So I've had my tank up and running with fish (9) for a month now. All my levels have stayed stable for 2 weeks, and I want to know if its safe to add more fish. Any advice?

Please tell us more about your tank &, well, everything!

Tank size, fish & sizes, water changes, tap water, etc. Did you ever see ammonia? Nitrite? Plants?

I know you've posted before but I don't recall just what you said or when.

So, I'm not familiar with the dimensions of a 23g, can you tell us again please?

All of your fish would like to be kept in larger numbers; 6 as a minimum for all your species; more would be better!...if there's tank space...but there might not be...floor space for bottom feeders (corys)? Side to side for schooling tetras?...otos? They're kind of delicate in a fussy feeding "on the glass" kind of way. All "can" be kept in a smaller tank...with the right balance...

NO!! Don't get (my favs) loaches to deal with a snail issue. They, like all your fish choices, would like to be kept in a minimum of 6. They, as all your fish, behave much more "normally" in bigger groups. Choose either 6-8 corys OR dwarf loaches...you don't have room for both.

We're trying to help you have balanced tank for the longer term. Think hard...if you can only have 3 species, which 3 will you choose? The biggest issue I see are dwarf loaches vs corys. Pick 1 of those 2.

What kind of snails are you worried about? I like a few...but they may need control...

I like ramshorn snails better than bladder snails. Both have pretty weak shells & can be smushed against the glass to kill them...unless you're very squeemish. The corys may eat the "leftovers". Both lay "jelly masses" of eggs; they can be scraped off & vacuumed out...but just scraping them off is not enough.

Trumpet snails have much harder shells. Less food for all snails is a first step to their control.
