Couple of Questions about Hypo
Couple of Questions about Hypo
Hi BNUMAIR,
I have a few questions about Hypo and the ich life cycle. I am running Hypo on 2 fish in my 20 gal. QT -a PJ Cardinal and Royal Gramma - as per your advice and instructions a few posts earlier on here. The PJ Cardinal was added on 8/21 and the Royal Gramma on 8/23. Waited a couple of days for them to settle and started Prazipro on 8/26. On 8/27 the RG started scratching. Cardinal has shown no signs of anything from Day 1. The RG showed no visible signs of ich, is eating well, very active, no heavy respiration. Just flashing, maybe hanging around by the PH side of the tank more than the HOB side, but the PVC keeps blowing over there and that's it's home. I assumed it might be in the gills and started hypo.
Once I got the SG down to 1.009 the RG stopped scratching (about 2 days later). I have been monitoring the SG with my calibrated refractometer on a daily basis and the SG is remaining at 1.009. Both fish remain active and eat like pigs. Now 10 days into Hypo, the RG started flashing again. I thought that would not happen again. The Cardinal is still asymptomatic and doing well. The SG has been stable at 1.009, almost 1.008.
Temp is at 78.4, NH4 0, NO2 0, NO3 0, pH 8.0
I have read all the posts I could find on here about Ich life cycle and the various treatment methods but I think I need a little further clarification. After the trophont falls off the fish and goes into the tomont stage (where I assumed the scratching would stop), once the cyst hatches and sends out the tomites into my now 1.009 SG water, would not the lower salinity then kill all those pesky tomites before they get a chance to attach themselves to a fish? I guess I am assuming that every single parasite in the tank is going through every phase of the life cycle at the same time. Is that not the case? Can there be multiple stages of the life cycle going on at the same time and THAT is why the treatment phase is so long? Is it normal to have a fish start scratching again after 10 days in hypo? Just want to be sure I am doing this right.
Also, do we do water changes during hypo? My QT is fully cycled and HOB is jammed with ceramic rings that I am not touching to rinse off until this treatment is done. Thus far I have had no ammonia problems and I am trying not to overfeed but they always seem like they are starving. I am feeding these two fish primarily mysis (about 1/3 cube 1xdaily) and trying to make sure there is nothing left floating around but I am sure I miss some and it gets lodged under the PVC along with their poop which collects there. One of the PVC pipes is like a Porto-Potty! And every time I try to siphon it out, the RG starts freaking out, trying to jump out of the tank, and I don't want to stress it anymore than it already is but I know I need to get the waste out. Should I try to remove the waste on a daily basis or should I let it ride for a week? Thanks in advance for your wisdom!
