#10gallon

Hello! My name is Jess and I'm new to owning ADFs. When I got this guy, he was already like this. His back has two uneven lumps to it. It's almost like his lower back is caved, and it makes his back look indented, like he has too much meat to his shoulders. One lumps is larger than the other...

I found this snail in my tank yesterday and have no idea what it is. These are the best pictures I could get of it. I would also be interested in knowing whether or not it’s invasive, so I can get it removed before it becomes a problem (if it hasn’t already).

PLEASE READ!! What would you consider to be a good light schedule for a 10 gallon tank with guppys? And if there anything else I need to know that has to do with lights? I have already bought the lights though so there's no worries in having to recommend me any lights. Any recommendations will help!

PLEASE READ!!! Hello, I am soon to become a new owner of 4 guppys in my 10 gallong tank! I'm interested in if anyone knows what other 2 fish I could get that fit the tank and are friendly towards guppys?
