Had an issue with a cat vs tank, cat won...tank busted. Now cats are not allowed in the basement and we are figuring out if the tank is salvageable. Thankfully we know someone who is an die caster, designer, inventor, drafter and troubleshooting is a hobby for him. He thinks he has a way to fix the tank. Sis and I hope its true as moving this beast will be a PITA as its is old and made of heavy non-standard thickness glass (custom built 5'x3', and bought used).
Fortunately there weren't many inhabitants (4 BN plecos, one royal pleco, 2 angelfish, one large catfish, and a small knife-fish) and we had a couple other large and medium tanks to temporarily move fish into.
If we can repair the tank (its a 120gallon) we will start the process of musical tanks, moving some tanks over to other over then next months to year. Sis was going to break down her 75 gallon acrylic and move the inhabitants to this tank, then we were going to move the rack of betta tanks over to another rack and set up the 120 acrylic in that area. The glass 75 gallon inhabitants (Peru wolf fish, BN pleco and wild blue acara would move to that tank, and possibly the female wild blue acara from the S. American 120. With both 75 gallon tanks empty the rack (and tanks) would be broken down, making space for a 180 gallon.
I was entertaining the idea of a 220-240 acrylic, but prefer the longevity of glass and for the same price I can get a 180, stand and aquarium movers to put the tank in the basement.
When I get this tank I will be moving some inhabitants out of the 125 and into the 180 (mainly the 2 royal plecos I have and a slew of other plecos (BN, peckoltia and the 3 beacon and green phantom) I would like to add an assortment of barbs, including the red pandas I currently have in the 125. I will also be breaking down the S. American 120 gallon I have and many of the tetras will be re-homed with some moving into the other 120 (with the broken center brace). The corys will move into the 180 and I will add another 7-10 brochis (hog-nose) cory into the tank.
With the S.American 120 empty I will turn the tank into a coldwater home for my golden and common weather loaches, the golden barbs and add some giant danios to the tank. This will allow me to break down the 50 gallon low boy and make some changes to the shelving unit that is holding it. We will be able to transfer the inhabitants form the 20L river tank into a 33 gallon or similar tank and place it in this area. We will also be able to set up a 40 breeder blackwater tank for the chocolate gouramis I have and add a variety of pangio loaches (regular, silver, black, myersi, zipper, hairband and possibly purple).
Sis and I agree that we like bigger tanks and with this we will loose two 75 gallons, a 20 long and a 50 gallon tank, gain a 180 gallon and a 33 gallon and make use of the 40 breeder we have sitting around.
Again these are future plans, funding needs to come together for the stand for the 120g acrylic, the 180g and the stand/movers for the 180.
