I have a few of the Purple girls still. They are between 5 and 6 months old. $25 would do it. That's with shipping included. I get $10 just for the Purple females on Aquabid but I give forum members discounts.
I love your Spongebob theme tank for DaBeDee! I saw a Spongebob figurine for aquariums at Walmart. You should totally add it in front of the pineapple house and make Patrick and Spongebob wave at each other!
Sorry it took so long... I'm usually on my iPod so I don't see these until I get on the computer..
Is it just the loaches and the pleco in the 10 gallon? This isn't something I would recommend (dojos usually get 10" long.. these species really shouldn't be kept together) but I would say since this has been this way for 5 years sort of an exception (maybe it's not a dojo, maybe it just didn't grow), to get 2-3 more kuhli loaches for the tank. It would be better to get sand..
Have you tested the water?
I have never let the pellets dry out. I don't know what it would do to the dosage.. I didn't have problems with immediate sinking on pellets I used. I used Hikari and Omega One. You can't use NLS for soaking..
You don't have to add it slowly, but I would predissolve it just because it's easier to dissolve anything that way and the fish don't get so much of a hit of it in one area as it breaks down.
