1~ I have 2 Peacock Gudgeons That have been scratching their sides on the substrate and other decorations and one of the two has a noticably larger, bloated belly. A third has been rather lethargic and tends to keep its fins pinned back and floats up toward the top of the tank. Their coloration all looks fine.
2~ The tanks water parameters are:
78 degrees F
3~ The tank is 45 gallons and has been set up for about 2 years.
4~ I am using a Marineland Penguin 350 hob
filter in combination with a submersible Pen-Plax 610 Cascade Corner Filter.
5~ My list of fish are:
10 Cardinal Tetras all less than 1",
5 Peacock Gudgeon about 1",
5 Otocinclus less than 1",
5 Black Kuhli Loaches all 3",
3 Ghost Shrimp all 1",
2 Dwarf Gourami both 1.5", and
1 Ivory Mystery Snail.
So a total of 31 fish.
6~ My last water change and gravel vac was yesterday. I do a 35% water change every5 days and I vac the gravel every 10 days.
7~ I have had all of these fish for anywhere between 2-4 weeks. Every fish was drip acclimated for a minimum of 2-3 hours.
8~ The only new addition to the tank is a small amount of Christmas Moss. However, I noticed the issues before adding the moss.
9~ I feed the fish a mix of TetraMin Algae Waffers, Aqueon shrimp pellets, Tetra Ciclid flakes, Tetra bloodworms, and once in a while some Omega One Brine Shrimp.
I have bought some Marineland All-in-One Remedy, but have not used it yet. If this is what I should be using, do I need to quarantine these fish or should I just treat the whole tank as a precaution? I don't have a quarantine tank yet.
