i just got my 4 new female retics yesterday and i did a test for the acclimation...i took one and suirt and dumped it...took the other 3 and did a fast drip for 15min then put them in the same tank as the dumped one...(to keep them on even grounds)...the ray that i dumped freaked out and was flipping when it entured the tank...it was very stressed, developed some tail fungus and die in the night...the other 3 were calm when i put them in, breathing normaly like i have had them for weeks...also to top it all off 2 of the 3 were eatting within 3hrs...the other one is a maybe eatting, but i have not confurmed it...also the biggest one had very sh^tty water when i got it...it was the first to eat after the 15min drip and is the most active...i can't wait to put some pics up as it has an amazing pattern that i haven't seen before...i have to wait for pics till my main computer is fixed though...
