same thing here, TAKE HIM am being VERY serious right now soon since your brother dosen't care for him he will get highly aggressive and gain popeye, i have a HMPK boy named "oceanist" he was neglected from my little brother .... he was in complete darkness, barely ever fed, never had clean water. my dad had to pitch in here and there to help.
i took oceanist in, i cured his aggression, but not his eye, oceanist has popeye, it is to late to save his eye. he had it for months and am doing my best with out medication. i know he is going to lose his eye, but i rather that then his life. face your parents and say" i have to take the betta (what ever his name is ) because he will die with out care, your brother is not caring for him and he will get a diesease if i (you) don't do something because he (your brother) won't do anything", even if you tell your brother to start to care for him, ther is a high percentage that he will still neglect because younger kids have no responsibility. because even RIGHT NOW that boy is suffering and easily could catch not just Popeye any disease. face your parents or your brother. i just said (at first) to my mom/dad " it is ok can i hold on to (your) brother's betta for a little?" if they say yes take him into your room (or where ever you put your betta's at) and firstly feed him he must be hungry and clean the tank after he is done eating. if your brother give you problems say something like this " well, if you (your brother) consider it as YOUR fish how about caring for it, you do not see anything wrong now but VERY soon he WILL get sick and die, BECAUSE of your (your brother) neglecting ways" do not be nice what ever you do DON'T " HE WILL DIE, i (you) happen to take WAY better care of him then you (your brother), if he catch pop eye or any disease you on your own (your brother) because i tried and you don not seem to care at all for him and he suffers, would you like it someone didn't clean you poop? would you like starve and to be very weak? would you like to be very sick that there is nothing to help you? (place your brother as if he was the betta) because i (you) happen to CARE for him and HELP him live" sorry it is a bit long, hope you get the point. i take betta's very serious
