Thank you all for the information. I have a few more things that I need to know about:
1 - If I'll get a 100L tank, which would be better? a 100 cm long x 40 cm wide x 30 cm tall tank or 60 x 60 x 30 cm (height) tank?
I think that the 60 x 60 would allow for more turns / bigger surface, but the 100 x 40 x 30 would allow for more swimming and yet my catfish usually stands in certain places, even when he had a bigger tank he would pick a side of it and stay there along with his buddy. But the longer tank would probably make the swordtails happy. Which would be better out of those 2 possibilities and also which would work better with a 30 cm height? As I've heard that there might be some problems with short and long aquariums when it comes to resistance.
2 - I have a 300L/h Boyu SP-1000I filter. It also acts as an oxygen stone by spraying it along with the water jet, which i find useful, as it doesn't need that annoying airstone added. Will it be ok for a 100L tank? Basically it would recycle the water 3 times an hour.
