I just had my 31st birthday this weekend and I've decided my present to myself is going to be a larger tank. I've had my 27 gallon for 20+ years now, and want to try something bigger. Petco has their dollar per gallon sale going right now, and I got a $75 gift card for my bday so I'll probably use that. I'm trying to decide between the 40 breeder, and a regular 39 gallon. I'm going to be planting, so I like the greater area on the bottom of the 40 breeder, but it also seems a bit shallow and I'm not sure if I like that. Is it hard to find a fluorescent hood for the breeders? That's another factor, I don't want to end up paying out the wazoo if supplies for the breeder are more expensive. Any thoughts?
