My girlfriend had to have blood parrot in the new tank so thats what we wound up with. Info on the tank its 100g with a fluvial FX5 canister, still need something else. sand substrate. some slate and driftwood. 24" bubble wand so everyone has enough oxygen, and all fake plants. Anyways we have three blood parrots about 3-4" and six green cory cats. the cory's are doing great but the parrots just hide and wont eat. i know they can go a while without eating but is this normal for blood parrots. I don't want these little guys to die, or just hide all the time either. i do reasearch everything i get and have been looking at these guys for about 3 weeks trying to get as much info before we bought but any info from someone with experiance with them would be appreciated
