We don't have a couch. When we got rid of the old one and bought a new one it wouldn't fit through the door, so we swapped it for another recliner. Most of the tanks are in the basement now, just the 30L BN farm and the 10 gallon fry tank upstairs. One of these days we'll move into a bigger house, and I'll have space to set up a huge show tank. I have 10 tanks running now, and really don't plan on setting up any more. I may upgrade a couple to larger sizes, but I have enough to keep me busy.
I found this precocious little bugger in the 38, yolk sac already gone. Apparently there was at least one egg that hatched significantly earlier than the rest.
The pH is 7.4-7.6; it comes out of the tap like that, and I use crushed coral to buffer it.
