Hi Evelyn
Thanks for replying. Yes, hopefully someone who knows about the safety issue of the hood might be able to help me.
Re my tanks - I'm definitely not overstocked - understocked if anything LOL.
I have a 3 foot tank (sorry, I don't work in gallons so I'll just give you the tank sizes), full measurement in inches (Lengh, Height and Depth) is 36L x 15H x 12D - and in this tank I have two small severums (the male is about 2" at present, female smaller), two African dwarf frogs (only about 1" in size and these won't grow much larger), one rainbow shark (about 3"), one female Betta (about 2") and one red tail shark (about 2.5"). The tank looks practically empty but I don't want to add any more to this tank. I am intending on moving one of the sharks out, as well as the frogs. I want this tank to mainly be for the severums as I know they will grow quite large plus when they are spawning they become very aggressive and constantly bully the other fish.
The other tank is 24"L x 18H x 12"D - in that I have just one lonely guppy at present. Have been told to keep just him in the tank for a week before adding the shark and frogs.
My smallest tank is a 12" cube - and this houses my male Betta.
