Thanks.
Back in the '70's I worked at a pet shop and raised cichlids at home, including Discus.
Kewl ... :thumbsup:
For tanks I had lot's of loboy 20's a few 50's, a 55 and a bunch of 10's. I usually bred them in the 10's.
My current inventory is (1) 100G Long, (2) 55G, (2) 20G Longs (loboy), and 4 10G's ...
I'm starting to get a little more focused on what I want to do and the direction I want to go in, in terms of species.
The 100G Long will get used as a display tank ... and may get built into a wall that divides two rooms (family room and fish room) so that it can be seen from both rooms. Not for sure on that yet, but it's under consideration as to whether I want to mess with it or not. Likely a Lake Malawi tank - either mbuna or haps/peacocks ... The rattier of the 55's will probably get used as a sump filter for 100G Long.
The other 55 will get used as a breeding set up for full-size Julidochromis - probably regani ("Kipili"/"marksmithi" and/or "Kachese"), possibly as a Tang community tank.
The two 20G Longs will be "species-only" for dwarf Julidochromis - transcriptus and ornatus
Three of the 10G's will get used as grow outs and the 4th as a hospital/quarantine tank.
Also want to do Julidochromis dickfeldi ("Midnight") but it would require additional tanks.
Of course, all of it is dependent on finding decent stock at reasonable prices. And finding decent tanks for a song.
Speaking of which, there was a 125G on CL yesterday that looked to be in great shape (no mineral deposits or cloudiness on the glass, full of water with a couple of Oscars in it) No stand (which I really don't care about) ... but with glass covers, lights, and two HOB filters ... for $100.

(They were moving out of state and needed it gone)
Only problem was that it was up in Detroit ... :laughing:
My method for "increasing the tank size" with a full brood of Discus was to set up the 50 and get it operating smoothly for a few weeks so it was stable. Then draw the water down enough in the 50 and the 10 so I could set the 10 gallon aquarium inside the 50 gently then gradually fill the 10 and the 50 gallon back up such that there was virtually no disturbance. Then when all the fish eventually swam out of the 10, remove the 10. Never got any complaints from the fish.
Yeah ... that sounds very workable.
I really don't like netting fish or otherwise disturbing them if I don't have to.
A full tank of Discus can be darn pretty.
Yup ... I've seen some videos of some really large ones breeding in a bare tank that a guy posted on another forum. They were very beautiful fish and it was neat to watch the interactions (there were around 6 - 8 discus in the tank)
