tangs??

I was thinking about getting one of those for my 46BF but I'm worried about the heat using Metal Halides (2X250).

 

That's an opinion, 5 wouldn't school as adults though.

 

yeah I would only use the front piece and then mesh the rest.

 

I wouldn't use them, they can hinder gas exchange, light and become a PITA cleaning, I just hate adding extra maintenance issues to a tank, and yes, it can cause heat issues, I'd stick with what ingtar stated.

Hence, why I said it was just my opinion. They are boring and will prob kill eachother, IMO. And is staying DEAD STILL, still considered schooling?

yupp, great idea, and this comes from a former glass top lover

 

Gas exchange is only an issue if you don't plan for it My 46 uses a sponge filter (which I do believe helps with gas exchange since it forces outside air into the tank and under the glass top, which forces the old air out), HOB 'fuge (thanks to Cosmo ), and a skimmer, which again pulls in fresh air. 10 gal QT has a glass top as well, but left the back plastic off and covered the openings with mesh. That tank again has a sponge filter, HOB filter and a skimmer.

Very little maintenance cleaning on the 46 that is almost completely covered though. I clean the glass top about once every 3-4 months. The 10 gal has some salt creep issues though, since it is open on the back as mentioned.

 

if one has a sump, gas exchange shouldn't be a problem either. I'm not one for using glass covers but I don't think they are the problem that they once were thought to be.

 

FYI PM me if you are looking for quality fish or corals - I make weekly trips to Peterborough from the Kingston area.

 

Most Tangs should not be housed in a tank that size, and if so it should be for just the younger years as they are only a few inches, tangs like and need lots of room to swim.

 

A smaller tang from the Ctenochaetus family would be fine as a permanent resident in a 72 I would think. Plenty keep them in 75's, and a 72BF is very similarly sized.

 

I agree, a tomini or kole would be ok.
