bro, think about it. . ur mom didn't mean to hurt you or ur hobby by adding in those new LS/corals. She just wans to make you happy, not knowing the consequences it will have on the tank. I think u sld visit LFS with ur mom in future and show her wad fishes are "good" for ur tank and wad isnt. Just take it as a family hobby. Its just like nowadays my dad will ask me. . wan to add more fishes not?? and then he will drive me down to iwarna to choose plus pay for it. . lagi best!
regards,
paul
