Well after being really discouraged and out of time the other night I stayed up until about 4am and finished the plumbing and fixed added valves to the input and output of the closed loop pump (Thank you Untamed for noticing that).
I was going to bed and thought I would go see my Stars and Stripes Puffer, "Crush", as I do every night. I couldn't find him. I looked all over the tank and finally found him in the PVC cave he usually sleeps in but he was not moving. Turned on the lights to find that Crush had passed away. I have no idea what happened, he was his usual playful, energetic self just hours earlier. This has been absolutely devastating. I did not end up sleeping at all the other night. I tested the water MANY MANY times trying to figure it out but found nothing out of the ordinary. Nothing has changed in his tank that I can find. I checked him all over and there were no marks on him. His eyes looked fine and same with his gills. I have never had a fish just die on me and I still can't believe he is gone
Crush was an incredible companion for the year I had him and he will be very, very missed. Its already weird to not see him come to the glass everytime you pass his tank and spit for food. Its so sad too that he died the night his tank was pretty much ready to go.
Anyways, really not sure whats going to happen now. Tank is ready for water testing but I just have not had any motivation for a few days now to even bother. My fiance wants me to keep going with setting it up and get my porcupine and eel in there but I am now seriously considering selling them and taking a break. Crush really was like family to us and its been so hard to see him go...
Sorry about the length of that. Its just been very upsetting.
