i have no canopy on my tank and its open for the most part here's a pic .



well I'm sick of losing fish due to them jumping I'm now debating to put a canopy on to try and keep them in ....

so far i have lost

yellow wrasse
4 chromis
3 fire fish
yellow spotted mandarin
one other wrasse but i forget the name of it ...


any one have an idea of why they may be jumping ?? I'm tired of losing fish this way
