Op nothing wrong with asking questions, but keep them short and to the point and you should get more response.
Don't start all your thread titles with capitals and mark them urgent or help, turns people off.
Try not to ask too many subjective or controversial questions cuz you'll get varied opinions and when a subject has been beat to death people don't want to answer, again.
Keep them a bit shorter, and don't aim for "can I get by with" bare minimum stuff, aim for overkill, like keeping 3 bass in a 450, or 2 fish total in your 180. I know this hobby is a hole encased in glass we throw money into, but to be honest if you want success you have to settle for less or find a way to make more out of what you got.
Keep up the good work, it is evident you want a good home for your wet pets. Sometimes if you Google something and get 2 different groups of people arguing opposite, you just have to try it and see what happens and be prepared to adapt. Adapt, improvise, and overcome is my life motto. People may try to put it in your head not to put a kelberi in a 180, but it will take a lot of time for it to outgrow it, and by that time you can save money and build a pond, or sell the kelberi, or you may get bored in general, or your tank may bust and ruin your entire bedroom and kill it. Go slow man, slowly, put the kelberi and the Oscar in there, see how they do and how you manage the bio, then try adding a small knife. Pick out what you want most cuz unfortunately we can't have everything as much as you try, until you're ceo of your own company anyway.
