Well. Busy few weeks. On Sunday, I went to my LFS and got two more harlequins. So now I have four harlequins, Harley (youngest), Quinn (oldest), Rain, and Bo. And a snail I named Joe. Don't even ask why.
Today I woke up to Sammy with a split tail that has black edging around the split, and Coral has his black dots on his tail nipped (or shredded) off. I think it is the plastic plants. I really need to get my mom to take me over to Petsmart later in the week to get real plants. I did put Melafix in to prevent infections (and I also got the two new fish and snail) in his tail. Max might just be the whole problem, although I lean towards the plants for Coral, and Max for Sammy. Neither be nor my parents can afford a new tank for Max or more guppies. I really don't know what to do.
Also, suggestions for another tank or more guppies ARE NOT HELPFUL, as I can't afford either. I do appreciate any other help you might be able to give though.
I'm not sure I want to keep with this hobby much longer. I've already failed thrice.
