What do you think and any ideas??!!?

Telling people how to care for fish is a great idea, but if you also made videos on how to breed certain types of fish I think that would get you noticed a bit more. There is a channel on youtube, I think it's called jazzy78910 (but that could be wrong), that makes excellent videos on how to breed angelfish and he has a few others; all of his videos are at least 50,000 views. Maybe try to model your videos after his? Personally I like voice-over a little bit more.
