When To Put More Fish In?

fidjet2 · Sep 2, 2011

I have a 90L tank which most recently had platies in it -2 days ago- i gave them away as i couldn't handle the breeding

so i changed the substrate to sand as i am wanting cory's and did a partial water change during this. I havn't turned the filter off since- apart from when i changed the water- and today all my tests were fine so i got 10 neon tetras. They seem to be happy and healthy, i sat there for 5 mins watching them dart everywhere to get the food

So i was just wondering when i could put some cory's in...and how many at a time- I am going to get 10 in there all up- and then add a dwarf gourami.

thanks

In a week providing results are good

And no more than 50% current stock

You're going for dwarf corys aren't you? I think 10 regular corys might be a bit too many.

Keep monitoring your water daily and assuming you have no water problems, I'd add 5 dwarf corys in a week. Then another 5 a week later, again assuming no water problems. And then I'd wait a few weeks at least before adding the gourami as they are quite sensitive to any problems. By this time your other fish will be settled and any problems with them hopefully will be apparent.
