I have a newly established 10 gallon tank which has a couple live plants and 3 neon tetras, with 2 red wag swordtails. I am looking to add either another fish or another non- fish creature but I’m not sure if I have enough space for them. Forgot to mention before but I also have 14 swordtail fry in a breeding box in the tank. They were born recently and I don’t know what I’m going to do with them either at the moment. Any help is appreciated, thank you.
