right, i planning to take the hood off my rekord 120, as i have serveral clip on lights lying around. also, i can then attach another external filter and it wil be easier for maintenece as i can just lift the clip on lights up. but they are only small and this would leave 90% of the tank surface open. my question is i have a small community set up, with gold barbs, harleqins, neons, (black and normal) WCMM, platies, ottos, clown plecs and an apple snail. now will any of these fish jump? (e.g are reknown for jumping?) and will the snail go above the water level (im sure it wont as it will die if it does that but some snails can store water so i wasnt definate) so any help would be amazing. esp quick replies.
