My last clown loach to die was 23 years old. I got it 20+s years ago at about 4-5 inches. It ws close to 12 inches TL. I keep my clowns in 1 50 gal tank. They were on a 75 until they outgrew it. You are keeping too few clowns and cannot see their normal behavior in the number and size tank you have. I now have only 10 which should be more. Unfortunately I am backing out of the hobby and they will be offered for sale shortly.
One can rave about Stability all they want, but it contains no nitrifying bacteria and is, imo, a waste of money, especially to keep adding it.
Seachem makes a mixed bag or products, Some good, some not so good and some useless, imo. I currently have (orused in the past)the following from SeaChem:
- Equilibrium- used only in tanks heavily planted which also have snails and shrimp.
- MetroPlex (Active ingredients: metronidazole (70%) Inactive ingredients: excipients (30%).
- Flourish when I first started with live plants I used it but, I gave it up pretty fast and have used Tropic ferts ever since.
- Individual ferts- used for a while until Tropica divided its ferts in two- one comprehensive and the other mostly Trace.
It is important to realize that most of the major product makers for Aquariums must compete on a product by product level. That also means, unfortunately, that their competing product may not be worth buying but they feel complleed to sell it anyway.
I have only kept 20-28 tanks from 5.5 to 150 gals over the last 23+ years. I prefer to get my information on a lot of things relevant to the hobby not from social media where I am absent or from forums like this one (for the most part). I instead prefer to read the scientific research papers as most have no axe to grind or products to sell. They want to discover the science.
And that vid Ceez posted is not worth listening to as it gets too much info wrong. When one uses a dechlor which contains an ammonia detoxifier, or an outright detoxifier, it converts the ammonia (NH3) and which is quite toxic into ammonium (NH4) which is less toxic but at elevated levels for any time can still harm fish. The problem is that the bacteria cannot process NH3 as efficiently as NH3. Also, dechlor is a reducing agent which means is takes oxygen from the water in order to work.
If one relies on social media or product advertising for their information, the odds are they are getting bad info. Anybody can say anything they want without review or fact checking. Getting a paper published in a peer reviewed journal is a stringent review process preformed by degreed independent experts in the relevant field.
I can link you to three such published papers and a couple of granted patent applications for Dr. Tim's One and Only/Tetra Safe Start but cannot find a single published peer reviewed study for Seachem Stability. There is a reason for that. Stability does not contain any live bacteria, it is a bottle of spores. The problem is that the nitrifying bacteria do not form spores. Moreover, it was discovered some time ago that there are ammonia oxidizing Archaea at work in oceans, brackish, fresh water and many aquariums as well as soil
After reading or watching most of the misinformation on aquarium sites and some social media, I took up a crusade years ago on some sites to correct the incorrect information re. the bacteria and cycling.
The 40 gal. tank described above is not what I would consider a healthy tank, especially for only 3 clowns:
From
https://www.seriouslyfish.com/species/chromobotia-macracanthus/
C. macracanthus is
gregarious, forms complex social hierarchies and should be maintained in groups of at least 5 or 6 specimens, preferably 10 or more.
When kept singly it can become withdrawn or aggressive towards similarly-shaped fishes, and if only a
pair or trio are purchased the dominant individual may stress the other(s) to the extent that they stop feeding.
That said it seemingly requires regular contact with conspecifics, a fact exemplied by a number of behavioural rituals which have been recorded consistently in aquaria (see ‘Notes’).
