Hello everyone. I'm new to the forum. Had my betta for 3 days now.
Before I got my halfmoon betta, I did a fair share of research to make sure my boyfriend and I were fully prepared to care for one. When the day came to purchase our tank, I made the decision to get plastic plants instead of silk. I know the pros and cons of each, and ultimately chose plastic over silk to prevent from fraying threads. With plastic plants I've learned that if the plastic is not sharp it should be fine and tear the fins, so when picking my decor I looked for rounded leaves instead of jagged or extremely pointed ones. However, I never did the "nylon test" to see if the plants would snag.
The reason why I am asking for your opinion about my plants is because today I discovered that my betta's dorsal fin looked ripped and more tattered than normal. When I purchased him he had a slight 'V' tear on his dorsal, but now there are several more tears. I've ruled out that this possibly may not be fin rot because his caudal fin and anal fin are perfect circles. I'm thinking maybe
my judgement about the sharpness/jaggedness of my plants were wrong and that this may be the cause of his frayed finnage.
In terms of setup, I'm keeping Mr. Caviar in the Marineland Crescent 5 gal. tank, with a heater, LED light, and filter. I've included pictures of Caviar's home, his before pictures, and what he looks like now. I hope you all can help me diagnose him, or if I should find him smoother plants!
