Hi everyone! for the first part I want to say that getting a new tank is not an option- we dont have the money. so I have 5 guppies in a 5g tank (they where babies) but now the are bigger (had em for a few months) and I have a betta in a 10g tank. I was thinking, he does not even use all the space, and he is quite a lazy fish, so he does not explore the tank too much. but since m guppies are more active, and are a bigger group, should i move them to the 10 g, and move my betta to the 5g? and I was also wondering, we have NO artificial plants in my betta's tank, but his tail seems to be torn quite a bit. and we did not get him that way. I feel so bad for halo(my fish) and I'm wondering if there are any low budget (0-30$) treatments for him, I don't know if it affects his swimming, if he's hurting, and I dont want him to suffer if he is already. I really need advice.
