Hey, Thanks for the reply.
First on your comment:
None of my fish were purchased at Petco. They are however the only place I have found in my area which provide a 14 day guarantee on the fish with an accompanying water sample. If they had a bad reputation of their fish dying why would they have a policy such as this? Might it put them out of business? Here take another free fish, it only cost us $25, good thing we sold you the previous one for $40, oh the one died too, it must be our fault, here is another one, see ya soon...
My question was in the nature of; can 2-3 blue hippos get along together in the same tank, hoping for that kind of advice.
With regards to "requiring" a minimum of 8 foot long tank for a Blue Hippo and those kinds of recommendations; Let's start with info available from most tank manufactures, the largest percentage of reef hobbiest are running a 50G and the two of the most common fish are the Blue Hippo and the Clown, I have a feeling you've been living in a GIANTIC aquarium a bit too long there buddy. My 420G DAS by your definition would still be too small.
Sure a Hippo tang needs alot of space, in fact he REALLY needs to be in the ...OCEAN....... however, if you put him in a tank he just wont get as big, which is why my 3 inch long, 12 month old, Blue Hippo, cruising across this 48" long tank takes him a little while.
It's just my opinion, but I think you should really consider the validity of your audience on these responses, if they are coming here for your advice would they really be spending $8-10k on an 8 foot long 240g, that's not a typical variation in this hobby. Average is in the high range of $2.5-5k/tank, which I am guessing is the typical visitor on this forum who very likely currently has or has had a blue hippo and a clown and a 50G tank or had something very close to that in the past.
Appologies for digressing. Thanks for your hard work replying to everyone.
I think, that it would be best to get help from another aquarist and a different thread. While this is not a discussion thread, I advocate quarantining all fish no matter what the source
