Two or three weeks ago, I had an issue with my 10 gallon divided tank where my SeDT boy would jump the divider and be with my HMDTPK. We resolved that issue, but the plakat hasn't been quite the same since. His color has paled dirastically and his fins have become increasingly ragged. The tears look clean and there's nothing that I can see that looks like a black line or fuzzy stuff around them. The decor consists of live plants and terracotta pot.
To make things worse, the tank currently has a cyanobacteria outbreak where I have to do more larger, more frequent water changes and feed less per the instructions of some of the people on TFK. The two bettas pretty much ignore each other (at least when I'm around), but I'm wondering if just having the SeDT there is stressing him.
I currently have no medications, but I can pick some up from Petco/Petsmart tonight or this weekend if needed. I also have a .5 gallon Critter Keeper that I can float for quarantine should medication be deemed nessicary.
Here's the tank's info:
What size is your tank? 10 gallons, divided in half with craft mesh and report cover spines. PK is normally on the side with the filter, but switched him to the side with the heater today.
What temperature is your tank? 78*F normally, upped it to 80*F today
Does your tank have a filter? Yes. AquaClear 20, set to lowest output and baffled with part of a pop bottle. Intake is covered by a pre-filter sponge. Tank is also moderately planted with live plants.
Does your tank have an air stone or other type of aeration? No.
Is your tank heated? Yes.
What tank mates does your betta fish live with? A SeDT male on opposite side of divider.
What type of food do you feed your betta fish? New Life Spectrum Betta Pellets
How often do you feed your betta fish? 1-2 pellets once daily, they are fasted over the weekend if I go home for the weekend (I live in a dorm)
How often do you perform a water change? Typically once weekly, twice weekly with the cyanobacteria.
What percentage of the water do you change when you perform a water change? Normally 50%, 75-90% with cyanobacteria. Fish are cupped durring larger water changes and completely reacclimated afterward.
What type of additives do you add to the water when you perform a water change? Normally Seachem Prime, switched to StressCoat yesterday. Also add .8ml Flourish Comprehensive 1-2 times weekly, not on the same day as water change.
Have you tested your water? If so, what are the following parameters? I'll add in the other test results later today after classes.
Symptoms and Treatment
How has your betta fish's appearance changed? Yes. Has paled dirastically and fins are torn/ragged.
How has your betta fish's behavior changed? Slightly. Seems to rest more than normal.
When did you start noticing the symptoms? Two-three weeks ago after encounter with tankmate, thought fins would heal on their own and color would return as long as water was kept clean. Fins have gotten increasingly worse (especially over past day or so) since and color is still very pale.
Have you started treating your fish? If so, how? Started using StressCoat at .2mL StressCoat/1 gallon water at water changes, increased temperature from 78* F to 80*F.
Does your fish have any history of being ill? No. Has a kink in spine close to the base of his tail. Doesn't seem to affect swimming, feeding, or other behavior.
How old is your fish (approximately)? Unknown. Purchased from Petco in August of 2012.
Thanks in advance for any help!
