I'm planning on crossing Wild-type tiger (like Super Tiger but not as large) with Red Tiger. I would expect that the Black and Red genes are on the same allele, with Black being dominant over red. So it should work like this; Expression - Black Striped x Red Striped Genes - Black/Black x red/red Offspring should be; 50% Black/red - expressing as Black Striped 50% red/Black - expressing as Black Striped Then one of those back to Red parents; Black/red x red/red Giving offspring; 50% Black/red - expressing as Black Striped 50% red/red - expressing as Red Striped. The same works for Orange eye, which is recessive. So Orange eye would be present but hidden in all of the first cross. depends what you do next on the cross back. Now... what about Blue..... how does blue work? Is it the flesh or the shell that is affected? I don't know this answer. I am expecting blue is recessive and that it is probably 2 or 3 genes combined producing different shades of blue. Anyone got thoughts?

Yeh, I think the two heater option is probably the way to go. Also considered getting an old oil heater in the garage just to take the edge off. Depends on what the people here agree is a problem. Nick, do you still get fluctuations and have you noticed a consequence? FlipAquatics on youtube seems has a fairly strong position that temp fluctuations of a few degrees are not an issue, he seems more concerned with heaters changing the temperature too rapidly than he does with temp swings overnight.

Hey all, first post here, thanks for having me. I have 3 tanks set up in the garage, 1 x 180L (300w heater), 1 x 80L (200W heater) and 1 x 60L (200W heater). All are kept at about 22'C normally. I am in Canberra though, and it gets cold overnight in Winter. Last night the temp dropped to -2'C outside. The garage is not well insulated and obviously gets cold inside. It seems that all 3 tank's temperatures dropped to about 19'C overnight and are slowly coming back up to temp now. I would expect they will reach 22 by about midday. All the shrimp, guppies and plecos seem fine this morning. What I have read and watched online says that temperature changes for shrimp is no big deal, as long as the change is gradual. I would guess the temp fluctuates less than 1 degree an hour, maximum swing of about 4 - 5 degrees. Can I get peoples thoughts and experiences on this topic, please? **Edited to Add - Currently have Red Cherry Shrimp, Blue Rili NeoCaridina and Cycling a tank for 'Blue Tiger' Caridina ***** Cheers Raf in Canberra
