Water since meds - .25 amonia - once was .5 before a water change
Temp 80-82
PH 8-8.2
GH?
KH?
He's about 13" in a 25 gallon - we've been waiting to put him in a 65 until he's better!
He's 10+ years old. No other fish.
Aquclear 50 & Tetra 40 - they need rinsing every other day when he's well & pooping like crazy!
Feed zuccini, tetramin, wood chips, peas.
Probably over feeding

Water change every 3-5 days depending on how dirty.
He has gravel & driftwood and mopani? wood.
This was all when he was well.
It's been a little over a month since he hasn't been normal.
He's been getting constipated every few months. Just for a day or 2. Sometimes a week. Last time was really bad so dosed for 5 days with epsom & he was back to normal for 2 months. Happened again - tried epsom again but didn't work. He was hardly eating. Slightly bloated but not too bad. Oh - he also always seems to get bulged out on one side - when you look from the front it's the left side. Seems worse when he's blocked up. Dosed 6 times (every other day) with kanaplex. He seemed to be a bit better. Pooped a bit, ate a bit but still not normal. Started metro with the 6th dose of kanaplex. Have given 2 more doses since then. Also added epsom to the water - 6 teaspoon for 25 gallon tank. Change about 1/3 tank water before every dose - amonia is always at .25 with meds - never had any before. Before the change it will be .5 Nitrite is 0. PH is 8-8.2 (always has been) Nitrate has been up at 20 but lately always 1-5. Dosed peas with metro garlic and epsom. Give 2x a day. Think he's eating some. Took wood chips & dosed with epsom. Tried feeding those too. What else can we do? He seems ok but is not eating or pooping normal! This has been over a month!!! Please advise! Thank you!
