20 Gallon Newbie Build

Hello everyone! Firstly, an introduction: My name is Matt, and this is my first time post in what will hopefully be a long fishkeeping life

I have recently graduated, and in doing so, upgraded my 10 gallon to a 20 long. In it I currently have 3 Dalmation mollies (2 female, 1 male) and four Rosy Tetras. I feel like I am on the verge of overstock due to the mollies, but my (relatively trustworthy) LFS seems to think I can fit at least 4 or 5 small-breed Cory's. I'm not so sure, but it brings up the question: what can I actually expect out of my newfound space? Any advice or thoughts are appreciated, and I'm glad to finally be a part of the the community I have used so often in the past!

 

• Edit: I am not quite a newbie, as I have kept a tank of at least 10 gallons for the last 3 years... Just relatively small ones!

 

Congrats on the upgrade and welcome! I’m not too informed about mollies but you can definitely put a school of cories in your tank. Like you said, go for the smaller species (Julii, panda, sterbai) and you could put a group of 6 in there just depends what temperature you keep your tank

 

Its a cute tank, I love my cory's and have 9 of them in a well established tank with mollies and others...main thing is add fish slowly, and watch your water parameters closely along with frequent water changes.

 

its a nice looking tank - but I am a sucker for live plants congrats tho it looks good.

Thank you! The Amazon Swords are live, and the intent is to introduce more live plants as I become more aquainted and sure of my plant keeping abilities. The other few are providing cover until such a time comes!

sounds like a really good plan - I almost have as much fun with plants as I do fish. but it is always good to take it slow and introduce plants as you develop a bit more experience.

Dont forget to use a little aquatic plant fertalizer early on until your tank cycles properly - just keep an eye on tank algae (a couple of snails can help if it becomes a problem)

Thank you for the insight and encouragement! Glad to know that I am on the right track with plants!
